Twisted has encountered one such issue, described here:
http://twistedmatrix.com/trac/ticket/1997#comment:12
Unfortunately, I don't know enough about signals to suggest or comment
on the solution. Any Python/C wrapper around a syscall which can be
interrupted needs to somehow atomically check for the presence of
pending python signal handlers; I don't know of any POSIX API to do
that.
