[issue4970] test_os causes delayed failure on x86 gentoo buildbot: Unknown signal 32

Antoine Pitrou <pitrou[at]free.fr> added the comment:

Prelude has had the same problem with signal 32:
https://dev.prelude-ids.com/issues/show/133
According to their research, it is due to the linuxthreads
implementation of the pthread API.

To know which threads implementation your glibc is using, you can run
"getconf GNU_LIBPTHREAD_VERSION" (on a modern system, it should print
something like "NPTL 2.9").

(of course, the question is, since the signal is used by linuxthreads,
why doesn't it get caught instead of killing the process?)

Antoine Pitrou <pitrou[at]free.fr> added the comment:

Sridhar, Neal, I would advocate disabling (commenting out)
test_closerange in Lib/test/test_os.py and see what happens.

That's the one really dirty test in test_os, it might close a file
handle linuxthreads is relying on.

Forget the last comment, test_closerange is fine...
