Right, I understand better now. Here is a secodn attempt:
http://ftp.espci.fr/shadow/manu/pthread.patch

I tried to avoid duplicating definitions between libc and libpthread,
with a preference for having a depencency on libc code in libpthread,
but it might not be the right approach.

There is also the case of pthread_cond_wait_nothread() which I 
completely moved to libc. I removed pthread__testcancel() and
pthread_mutex_unlock() calls since I could not see how they could
be useful, as this is called only when there is a single thread.
