History
Angus Salkeld 5828bee144 aisexec crash on exit 
Cause:
As part of its exit procedure, ais cancels its worker thread then manually
processes any outstanding items that were still in the worker thread's queue.
The worker thread has a low priority so normally it does not execute any
further before ais finishes exiting, but if the main thread's exiting is
delayed for any reason, there is a chance the worker thread could execute and
try to process items which have already been processed and freed by the main
thread - often leading to the worker thread seeing NULL data and ultimately
causing a segmentation fault.

Fix:
Modified worker_thread_group_exit() so it does a pthread_join() after the
pthread_cancel() call, so that the worker thread always shuts down cleanly
before the main thread does its cleanup.
