The threading implementation (LinuxThreads) of your glibc is what is
causing the problem. You can "fix" the problem by one of two means:
- Run with a newer, NPTL-enabled glibc. To stay on Debian, I belive
this would entail upgrading from Woody to Sarge. I am only lightly
familiar with Debian, so perhaps somebody can correct me?
- Install an alternate threading package, and compile Python to use
it instead of the default one in libc. Note that I have *no* idea
how to do this even on systems where I am more comfortable than
with Debian.
