Steve, yes, the
-threadoption to ns_schedule_proc (which
ad_schedule_procjust passes along) is what I referred to above. If I remember correctly, that starts up a new thread for every individual run of the job, and then kills it. If the main scheduler thread is locked up, will the thread for the new job ever get spawned? I'd need to test it, but I suspect the answer is no, it will not.
