I've never had anything but trouble with them. They are user-land threads, so must cooperate for any kind of concurrency. I'm trying to get Postgres to replicate using Slony-I, and that is a threaded app. On FreeBSD 4.10, it locks up inside some threading library routine. On FreeBSD 5 it works fantascitally. I hear on FreeBSD 4.9 it also works.

FreeBSD 5 threads are awesome. They are scheduled at the kernel level and offer very good concurrency.

Thanks, Vivek. Perhaps I'll ask my hosting provider for an upgrade. Is FreeBSD 5 stable now?
