It's a compile time option with a default of 250 since 2.6.13... :-)

I second that, especially since the game is not restricted to linux
platforms. But a granularity of 10ms seems to be common, sometimes it
is better, sometimes configurable. Therefore optimizing for a scheduler
granularity of 10ms should help on many systems. So I'd say we should use
a framerate of 33fps.
