Just because there's no "portable" way to be sure it'll work doesn't mean
there's no point in trying. If one user sets it to 5ms and it's effective for
him there's no reason to take out the option for him just because it doesn't
work out as well on all platforms.
Linux, for example has moved to higher clock speeds precisely because things
like movie and music players need to be able to control their timing to much
more precision than 10ms.
