Subject Futex
Date Thu, 23 Nov 2017 19:01:58 GMT
Was doing some timing with futexes (we used them a lot in a previous life
in database engines) and they're consistently about 20-30% faster than
standard mutexes in Linux.

However, it seems like this is not worth making a change since mutexes
don't tend to get called so much that it would seem to make a noticeable
difference, although I could be wrong -- so far besides the queue, I am not
aware of any major bottlenecks on mutexes.

Any thoughts?
