/* Thread package.
This is intended to be usable independently from Python.
The implementation for system foobar is in a file thread_foobar.h
which is included by this file dependent on config settings.

* Makefile adapted to changes below. * split pythonmain.c in two: most stuff goes to pythonrun.c, in the library. * new optional built-in threadmodule.c, build upon Sjoerd's thread.{c,h}. * new module from Sjoerd: mmmodule.c (dynamically loaded). * new module from Sjoerd: sv (svgen.py, svmodule.c.proto). * new files thread.{c,h} (from Sjoerd). * new xxmodule.c (example only). * myselect.h: bzero -> memset * select.c: bzero -> memset; removed global variable

Make better use of GNU Pth -- patch by Andy Dustman. I can't test this, so I'm just checking it in with blind faith in Andy. I've tested that it doesn't broeak a non-Pth build on Linux. Changes include: - There's a --with-pth configure option. - Instead of _GNU_PTH, we test for HAVE_PTH. - Better signal handling. - (The config.h.in file is regenerated in a slightly different order.)
