#8407 changed the wakeup fd: it now contains the signal number. pthread_sigmask() is now part of Python 3.3 (see also #8407).

signalfd() has advantages over the wakeup fd (msg103326):

 - it is handled in the kernel, the process is not interrupted. For example, system calls cannot fail with EINTR.
 - it gives much more information than the signal number (see signalfd_siginfo structure)
 - it is also possible to have several signalfds, each with a different signal mask. set_wakeup_fd is limited to a single fd per-process.
