Summary: more POSIX signal stuff
Initial Comment:
I got annoyed with Python not having sigsuspend et al,
so I wrote this.
It's not finished yet:
it doesn't do autoconf checks, so if you don't have
posix signal handling, it ain't gonna compile)
it doesn't do docs.
it doesn't do full-on sigaction (because that's not
what I was after).
but first I thought I'd see if any of the more unix
savvy Pythoneers (Martin? Barry?) could see any
enormous flaws in the approach...
It does seem to work, so far.

The patch looks good; please apply it.
It would be good if you copy the doc strings into libsignal.tex.

And here are the docs. I've even done a section for whatsnew!
The table looks a bit wierd in the html, but I don't think
it warrants concern.
I think I'm done now. Assigning to Martin for review, but
anyone with access to unices other than linux/x86 is
encouraged to test!

I think I'm done now. The patch I'm attaching
(a) does all the stuff my last patch did.
(b) uses the presence of sigprocmask to assume that all the
other posix-y stuff is there. I don't know if this is safe,
but I don't know what would be.
(c) adds tests
(d) adds a Misc/NEWS segment.
The patch I'll attach in a minute has the docs.

Hmm, I don't think I'm going to bother with sigaction. Most
of the options just don't make sense given when Python
signal handlers get run.
So, docs and autoconf hackery (spit) to go...

Try this instead. Definitely a good call on the interface
front.
Still same caveats.

Hmm, fair point. I just got carried away :)
Patch later.

I wonder whether we have to expose the API for signal sets.
Couldn't we just use lists/tuples of integers? This ought to
be similar to the processing of FD_SETs in select.
