I do recall thinking that this was the best way to handle signals with
threads. Just have all threads but one block all signals (that they can),
and leave that one thread as a signal handler. There is a section in the
POSIX book on pthreads that discusses threads and signals, but I don't
remember much other than the signal-handler thread method. If people are
interested, I can re-read it and summarize the chapter and post it here
later tonight/tomorrow.
