And do you guys actually use a recent glibc snapshot? Do you ever expect
to? Do you ever expect to run a third-party specialized web-server or
database library? All things that can use futex'es, and probably will.

I will strongly argue against making futexes conditional, simply because I
_want_ people to be able to depend on them in modern kernels. I do not
want developers to fall back on SysV semaphores just because it's too
painful for them to use the faster alternatives.
