[M3devel] [M3commit] CVS Update: cm3

[Jay K]

Interix is Posix (mostly) on NT, with fast fork.

  Cygwin in comparison is very slow.

  However SIGINFO is not available. Nor is "direct suspend" using a pthread_t I believe.

The older Interix version on XP does not allow access to any Win32 functions.

Newer versions do.

This does seem to be a pretty useful platfom.

Gui should be available too, but I have to work around some problem.

This whole interix thing is pretty messy.  Why do we care?  If you are on Windows just use Windows threads.   No need to pollute the pthreads code base with unnecessary complications for weird hybrids.

Modified files:
cm3/m3-libs/m3core/src/thread/PTHREAD/: ThreadPThread.m3 

Log message:
keep two thread handles
what to call them is unclear
here we ahve:
joinHandle
suspendResumeHandle

aka:
pthread
ntthread

on all but Interix (and possibly Cygwin), they are equivalent,
either the result of pthread_create or pthread_self

on Interix, once is pthread_create/self, the other is a kernel handle
for suspend/resume

alternate names welcome
the intent seems hoky, but helps much
