Python signal delivery under BSD 4.4

At some point, the threads implementation got changed so that new
threads get their signal mask set to "block everything and it's cat"
(there was a reason for this, but I'm not really sure what it was).
As I see it, you have two options: 1) write a little C to unset the
procmask after fork() but before execve() 2) only launch apps from the
main thread.

I did write wrappers for sigprocmask & so on for inclusion in Python
2.3, but the x-platform behaviour was insane (and *some* version of
FreeBSD contains fixes to libc_r that my code provoked, but I'm not
sure which version) so the code got backed out again.

Cheers,
