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)
[Class variables:]
HostName <String> remembered hostname
DomainName <String> remembered domainname
SlowFork <Boolean> if set, fork and popen are avoided;
(more or less obsolete now)

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.
fdArray 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[0] == StdIn for child
fdArray[1] == StdOut for child
fdArray[2] == StdErr for child
on VMS, these must be channels as returned by createMailBox.
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.
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
