FPS locker improvements

[Edge100x]

We've made some additional kernel tweaks and updates to our FPS Locker system, which benefits all managed/standalone game servers that we host on Linux and most noticeably games that run at high tickrates (such as our "ultraaccelerated" CS 1.6/DoD/TFC servers). The result is lower CPU usage and more stable FPS -- now within +/- 5 FPS at all times on most 1000 FPS servers. Take this output from a busy DoD server just now, for instance:

(Numbers will be a bit more variable on VDSes than bare hardware, since their emulated timers aren't quite as precise and there's more multitasking going on with other customers.)

Give it a try for yourself and let us know what you see!
