Yes. They call pthread_detach when ending, i.e. just before calling 
pthread_exit. So if you use normal threads, you already use that.

Similarly, pthread_join is a part of tthread.waitfor .  Have a look at 
rtl/unix/cthreads.pp for how the RTL threads map to pthreads on *nix 
systems.

Maybe there are other uses of pthread_detach that don't immediately call 
_exit.  I'm not pthreads expert, so I can't help there.
