In addition to what Dom has already answered - there are very significant
differences between the multithreading as implemented in the Windows OS
family and the varioius threading implementations for Linux like classic
libpthreads, Linuxthreads, NPTL, Mozilla and more.  If we legally could
look at MS's code I'd not expect to find much useful for us there ...
