Uses pthread_getthrds_np (so requires pthread linked, by default on ZTS, needs to be added for NTS). The stack size part is weird, but works in testing. An alternative approach is using procfs, but I didn't bother with this due to it not working on PASE (and the pthread approach works for the main thread too).
