this class realizes access to most (all ?) required operating system services;
some of it is very specific for unix, so do not depend on
things available here in your applications
- some may not be found in other OS's or be slightly different ...
(On the other hand: I do not want to hide all features
from you - in some situations it MAY be interesting to be
able to get down to a select or fork system call easily (at least on Unix systems).
You decide - portability vs. functionality)

exec:aCommandPathArg withArguments:argColl environment:environmentDictionary
fileDescriptors:fdColl fork:doFork newPgrp:newPgrp inDirectory:aDirectory
"Internal lowLevel entry for combined fork & exec;
If fork is false (chain a command):
execute the OS command specified by the argument, aCommandPath, with
arguments in argArray (no arguments, if nil).
If successful, this method does not return and smalltalk is gone.
If not successful, it does return.
Normal use is with forkForCommand.
If fork is true (subprocess command execution):
fork a child to do the above.
The process id of the child process is returned; nil if the fork failed.
fdColl contains the filedescriptors, to be used for the child (if fork is true).
fdArray[1] = 15 -> use fd 15 as stdin.
If an element of the array is set to nil, the corresponding filedescriptor
will be closed for the child.
fdArray[1] == StdIn for child
fdArray[2] == StdOut for child
fdArray[3] == StdErr for child
on VMS, these must be channels as returned by createMailBox.
All filedescriptors not present in fdColl will be closed for the child.
If newPgrp is true, the subprocess will be established in a new process group.
The processgroup will be equal to id.
newPgrp is not used on WIN32 and VMS systems.
environmentDictionary specifies environment variables which are passed differently from
the current environment. If non-nil, it must be a dictionary providing
key-value pairs for changed/added environment variables.
To pass a variable as empty (i.e. unset), pass a nil value.
Notice: this used to be two separate ST-methods; however, in order to use
vfork on some machines, it had to be merged into one, to avoid write
accesses to ST/X memory from the vforked-child.
The code below only does read accesses."

lockFD:aFileDescriptor shared:isSharedReadLock blocking:blockIfLocked
"set a lock on the file represented by aFileDescriptor.
(such as returned by ExternalStream>>fileDescriptor).
On some systems, only advisory locks are available -
these depends on other accessors to also perform the locking operation.
If they do not, they may still access the file
(on some systems, locks are mandatory, on others, they are advisory).
The isSharedReadLock argument (if true) specifies if multiple readers
are to be allowed - if false, they are not.
On some systems, all locks are non-exclusive locks.
Returns true, if the lock was aquired, false otherwise.
Notice, that not all OS's support these locks;
on some, this may simply be a no-op.
Also notice, that some systems block the process, to wait for the lock.
This can (again: on some systems) be avoided by passing a false blockIfLocked
argument."

Do not depend on the amount and contents of the returned information, some
systems may return more/less than others. Also, the contents depends on the
OS, for example, linux returns 'ix86', while WIN32 returns 'x86'.
This method is mainly provided to augment error reports with some system
information.
(in case of system/version specific OS errors, conditional workarounds and patches
may be based upon this info).
Also, applications could enable/disable buffering or otherwise reduce
their memory usage depending upon the amount of memory installed.
Your application may make use of available information for tuning,
but should NEVER DEPEND upon this in any way.
The returned info may (or may not) contain:
#system -> some operating system identification (irix, Linux, nt, win32s ...)
#version -> OS version (some os version identification)
#release -> OS release (3.5, 1.2.1 ...)
#node -> some host identification (hostname)
#domain -> domain name (hosts domain)
#machine -> type of CPU (i586, mips ...)
those are currently returned on some machines (no warranty)

#sharedRam -> amount of memory which is shared among processes

#bufferRam -> amount used for buffers
#swapSize -> total size of swap space

#numberOfCPUs -> number of cpus in box
