I still have 3 exams this month, and then I'll be here for 5 months :-)

There is already some work in libgcc: have a look at gthr* files in gcc's 
directory:
gthr-aix.h
gthr-dce.h
gthr-posix.h
gthr-rtems.h
gthr-single.h
gthr-solaris.h
gthr-vxworks.h
gthr-win32.h
gthr.h   ->  /* Threads compatibility routines for libgcc2.  */

I don't know wether we could use this lib for a system independent thread model,
but someone whispers that's in this direction we should scratch...
