The transitions of a thread state from PT_STATE_BLOCKED_QUEUE to
state PT_STATE_RUNNABLE looks a little bit rocky.
(An example would be pthread_cond_signal())

   It does not involve a pt_statelock
	
   There is a time-window where no locks are held and
	- the thread is still in state PT_STATE_BLOCKED_QUEUE
	- the thread is already removed from the sleep queue
	- the thread is on the way to the run queue

If pthread_suspend_np is called during this time window it could screw
up the sleep,run and suspend queue.
