I opened this issue for buildbots. If the test suite doesn't fail 
anymore because of a SIGALRM or SIGUSR1, we may miss a bug in a test, or 
a real bug in a module. I don't think that anyone will read the output 
of all builds.

I patched faulthandler for this issue: I added a chain argument to 
faulthandler.register() to call also the previous signal handler. I 
prefer to call the original signal handler to not change the current 
behaviour of the test suite.
