Quoting from the HEAD thread.cc file:
In pthread::create:
{
/* FIXME: set the priority appropriately for system contention
scope */
if (attr.inheritsched == PTHREAD_EXPLICIT_SCHED)
{
/* FIXME: set the scheduling settings for the new thread */
/* sched_thread_setparam (win32_obj_id, attr.schedparam); */
}
ResumeThread (win32_obj_id);
}
So the answer is: It's not implemented yet :-/.
given the code to do it is present, but commented, I'd suggest I
encountered a bug with it, and disabled it for reliability -
unfortunately I don't recall what issue I did have.
