"Programming with POSIX Threads" has this to say on the subject of
threads & signals:
"When writing threaded code, treat signals as Jabberwocks -- curious

Create a pipe, have your thread call select() with a timeout of five
minutes, have the signal handler write to the pipe. It may not be the
most elegant solution, but it should work.
