Re: pthread_mutex_unlock (was Re: sched_yield() makes OpenLDAP slow)

To fix the current problem, you can substitute usleep(0); It will
give the CPU to somebody if it's computable, then give it back to
you. It seems to work in every case that sched_yield() has
mucked up (perhaps 20 to 30 here).

That sounds like a terrible hack.

What cases has sched_yield mucked up for you, and why do you
think the problem is sched_yield mucking up? Can you solve it
using mutexes?

Thanks,
Nick
