Just to be clear: the approach I was suggesting is to have a resident
thread dedicated to signal management, not to spawn a new one when
needed. Another advantage is that we could mask signals in all threads
except this one, and have a consistent cross-platform behavior with
respect to signals+threads.

However I see two drawbacks:
- it seems that we want to allow building Python without threads
support. In that case, this wouldn't work, or we would need the
current implementation as a fallback, but this would complicate the
code somewhat.
- the thread would have to be respawned after a fork()

Hmmm, I'm not convinced by this argument in this specific case: since
the C version is now the default, is faster and more reliable, can't
we drop the Python version?
