Patch: BUG in thread_queue_apc()

[Martin Wilck]

The patch below fixes a bug in server/thread.c that causes
APCs to be "forgotten".

The patch is against today's CVS (2002-01-08).

I came across this by testing async file I/O. When submitting several
async IO requests, the IO completion routine was called only once for
the first submitted request.

I cannot oversee if this can break anything elsewhere, but I strongly
believe the behaviour with this patch is more sane than without.
