Hi,

Looking at this code, I don't see any obvious holes and it all seems
correct.

One thing you should perhaps consider is whether this change (using
sigaction, signal sets, instead of the antique signal(), etc.) might break
compilation on some antique UNIX machines or on MS-Windows (!?) or
something. But I doubt any present-day system actually lacks sigaction()
and friends, so I think your code is good.
