Tcl Source Code

Here is a patch to implement Cygwin support
for threading. Cygwin does not have the
_beginthreadex and _endthreadex methods.
Instead, it uses the CreateThread and
ExitThread APIs directly. Cygwin uses
a different runtime than msvcrt so it should
not suffer from the runtime memory leaks
that haunt the msvcrt code.

        * win/tclWinThrd.c (Tcl_CreateThread,
TclpThreadExit):
        When building under Cygwin, call CreateThread
instead
        of _beginthreadex and call ExitThread instead
of
        _endthreadex. Cygwin does not support these
msvcrt
        methods and does not suffer from the memory
leak
        problems that prompted their use.

haunt?  get it straight.  I don't pick on other peoples 
OSes, so shut your trap.

1) msvcrt use thread specific data.
2) needs to track when a thread starts.
3) needs to know when a thread goes away.

keep your tainted opinions to yourself.
