Take 2 is attached. I got rid of the 'locked' field and finally reverted to
my first idea, i.e using an API similar to both Win32-threads and Pthreads
because:
- for once the two worlds agree, let's try not to create a third one,
- the implementation is lighter, with one less indirection level,
- less prone to heap memory corruption.

Compiled under DJGPP and Mingw32.
