Hmmm... I guess it is cleanest and safer if the interruption procedure 
is totally handled by the thread subsystem. Previously I had to move 
some parts of the interrupt procedure in the java code as pthread_lock, 
pthread_conds are not guaranteed to be interrupted by a signal (what 
about other syscalls ? I think I've turned the problem around in 
jthreaded syscalls too...). But I had to modify the suspend procedure 
too in jthread_suspendall and introduce some way to catch 
pthread_mutex_lock and signal_wait so maybe it is time to put it back in 
  the thread layer.
