What about platforms which don't have <linux/futex.h> ?
Right now, xorg-server cannot build without xshmfence, and xshmfence cannot
build without Linux-only API's. There needs to be some way for Solaris,
BSD, MacOS and Cygwin to build without this, whether it's making xshmfence
optional for xorg-server or making xshmfence work with mutexes or other
portable API's.

This is a tiny library that exposes a event API on top of Linux
futexes. There was some discussion about using eventfd instead of this,
but the cost of adding two FDs to the X server for every DRI application
seems excessive, and by using PresentIdleNotify events, I've worked
around the limitations of futexes.
