pthread_suspend_np is safe, but may suspend the interrupt handler.
There are maybe situations where this is useful. For example:
interrupt_handler:
do low level stuff
suspended_thread = pthread_self();
pthread_kill(highpriority_handler_thread,RTL_SIG_WAKEUP);
/* now switch to thread that does the work*/
pthread_suspend(pthread_self());/*handler will wakeup*/
return;
