`Process`: revert `#interruptWith:`
Commit
3b02b0f1f647: Cherry-picked `Semaphore`, `EventSemaphore, `Process` and `ProcessorScheduler`
changes `Process >> #interruptWith:` but this - for not yet known reason - breaks
stx:libjava tests. This commit reverts the code to version before that commit,
fixing tests.

documentation
"
instances of me are used to interface to external library functions (as found in a dll/shared object).
Foreign function calls are based on the FFI library if available.
A limited fallback implementation is provided for systems with no libffi.
(this may have limitations on the supported argument types; for example,
the x86_64 fallback does not support float/double arguments).
Therefore the fallback should be considered a temporary workaround,
until libffi has been ported.
Inside a method, when a special external-call pragma such as:
<api: bool MessageBeep(uint)>
is encountered by the parser, the compiler generates a call via
<correspondingExternalLibraryFunctionObject> invokeWithArguments: argumentArray.
and the correspondingExternalLibraryFunctionObject is kept in the literal array.
In the invoke method, the library is checked to be loaded (and loaded if not already),
the arguments are converted to C and pushed onto the C-stack, the function is called,
and finally, the return value is converted back from C to a smalltalk object.
The parser supports the call-syntax of various other smalltalk dialects:
Squeak / ST-X:
<cdecl: [async] [virtual|nonVirtual][const] returnType functionNameStringOrIndex ( argType1..argTypeN ) module: moduleName >
<apicall: [async] [virtual|nonVirtual][const] returnType functionNameStringOrIndex ( argType1..argTypeN ) module: moduleName >
Dolphin:
<stdcall: [virtual|nonVirtual][const] returnType functionNameStringOrIndex argType1..argTypeN>
<cdecl: [virtual|nonVirtual][const] returnType functionNameStringOrIndex argType1..argTypeN>
ST/V:
<api: functionName argType1 .. argTypeN returnType>
<ccall: functionName argType1 .. argTypeN returnType>
<ole: vFunctionIndex argType1 .. argTypeN returnType>
VisualWorks:
<c: ...>
<c: #define NAME value>
"
!
example
"
[exBegin]
|f|
f := ExternalLibraryFunction new.
f beCallTypeWINAPI.
f name:'MessageBeep'
module:'user32.dll'
returnType:#boolean
argumentTypes:#(uint).
f invokeWith:1.
[exEnd]
Synchronous vs. Asynchronous calls:
by default, foreign function calls are synchronous, effectively blocking the whole ST/X system
(that is by purpose,because most C-code is not prepared for being interrupted, and also, normal
code is not prepared for a garbage collector to move objects around, while another C thread might
access the data...).
Therefore, the following will block all ST/X activity for 10 seconds
(try interacting with the launcher while the Sleep is performing):
[exBegin]
|f|
f := ExternalLibraryFunction new.
f beCallTypeWINAPI.
f name:'Sleep'
module:'kernel32.dll'
returnType:#void
argumentTypes:#(uint).
f invokeWith:10000.
[exEnd]
if you know what you do and you do not pass any possibly moving objects (such as strings) as argument,
the call can be made asynchronous. In that case, ONLY the calling thread will be blocked; all other smalltalk
threads wil continue to execute.
(try interacting now with the launcher while the Sleep is performing):
[exBegin]
|f|
f := ExternalLibraryFunction new.
f beCallTypeWINAPI.
f beAsync.
f name:'Sleep'
module:'kernel32.dll'
returnType:#void
argumentTypes:#(uint).
f invokeWith:10000.
[exEnd]
