As no one replied last time, here's this email again. I've found that I cannot work around select() not being a cancellation point on FreeBSD in my code - I had to #ifdef __FreeBSD__ in a hack which manually calls pthread_testcancel() every second. This is *nasty*! If there's any alternative, I'd very much like to hear it. Preferably I'd like to see select() made a cancellation point or a new form of select() eg; select_tc() added.
