Well,  on Linux, condition vars and semaphores are implemented
in terms of futex, http://en.wikipedia.org/wiki/Futex  (and spin locks,
I guess), as this is low level syscall.
Critical Section and Event, sounds like Windows. This is probably
implemented in Lazarus in terms of Linux constructs
(mutexes,condvars/semaphores).
