They conform to posix threads standard. recently freebsd has acquired a native threads package which is known as a hybrid threading package--it muliplexes user-space threads across _multiple_ processes--typically 1 per cpu--to take advantage of smp. freebsd native threads _also_ have a posix-conformant api. last I heard john dyson was writing the package... but i'd be interested in further status information myself.
