Threading part of the NTL M-on-N threading library is ready.


Although not without problems - there is no scheduler (well, there is round-robin one, which is not what I want), I did not run any kind of benchmarks to test SMP scalability and timer signal overhead (the latter is the most problematic part - although 'top' shows zero CPU usage for pool of 100 threads sleeping in infinite loop, it is still possible that actual CPU usage due to signal delivery overhead can be noticeble).

Code does not contain kevent syscall wrappers yet. I will think about dynamic library loading tricks, which allow to 'replace' syscalls in runtime.

Enough for today - I'm going climbing.
