Err, wait, that was slightly wrong... You need to:

 1. Block signals you're interested in on all threads, usually done
    early on, before starting any threads. Using pthread_sigmask.
 2. Create a new thread, and call sigwait in that thread on the
    interested signals, in a loop, handling signals as they come in.
