However, this deadlock leaves the system pretty hosed and you have to reboot to recover. Not good for real-time priority-preemption applications like our telephony application, with 90+ real-time (SCHED_FIFO and SCHED_RR) processes, many of them multi-threaded, interacting with each other for high volume call processing.
