FreeBSD currently has a userland thread implementation.  Threads
are not scheduled individually.  FreeBSD-CURRENT will move towards
a scheduler activation-based design; this is the KSE project.

OpenBSD's thread library is more or less the same as FreeBSD's.

I don't think NetBSD has (had?) a default thread library, but there
have been various competing implementations.  Ask a NetBSD person.
