Sorry for the confusion, I was unaware of FUTEX_FD! That said, I didn't test it either, but it looks similar to what I have been wanting. I suppose what I am wishing for is for this to be in the POSIX thread API itself, but that's asking for a great deal.

Kernel events without kevents Posted Mar 16, 2007 15:53 UTC (Fri) by cventers (subscriber, #31465) [Link] I think I remember reading something on LKML about FUTEX_FD beingbroken...
Kernel events without kevents Posted Mar 16, 2007 15:58 UTC (Fri) by pphaneuf (guest, #23480) [Link] Since it doesn't see any use in the mutex API that everyone uses, it's not surprising... Code that's not used tends to rot. Too bad, I would like that. I'll stay with my "pipes as semaphores" trick in the meantime...
Kernel events without kevents Posted Mar 16, 2007 16:47 UTC (Fri) by bronson (subscriber, #4806) [Link] You're right. Apparently it's "unfixably racy" and will disappear in June 2007.

And it looks like there's no alternative other than self-pipes. Arg!
