This statement does not make sense.  Because MySQL uses threads and
runs fine has no implication on how the threads are implemented.  None.

Processes distribute fine.  Threads are all within one process.

There are many systems out there with perfectly functional thread
libraries that are not kernel-based.  Just look at those wonderful MIT 
pthreads distributed with MySQL for a prime example.  There is no
kernel support used nor required.

This holds true for BSD/OS as well.  All threading is done in the
pthread library itself in user-space.
