Original commit message from CVS:
added a test for pth and pthreads. in summary, it doesn't work because
in __pthread_find_self() some funny stack pointer math is done that
will result in no matches for __pthread_find_self(). this is dereferenced in
__errno_location, causing a segfault on context switch because of the errno-swapping
on the part of pth. it's a mess and i don't know how to get around it. i'll
have to look into what ngpt does for looking up errno, as it has kernel threads as
well as user threads.
Original commit message from CVS:
The core code from pth has been taken out and included in gstreamer.
This code is documented, more or less, in http://www-124.ibm.com/pthreads/docs/rse-pmt.ps.
This code is designed to replace cothreads.[ch], eventually.
