i had the same idea yesterday :)
(but i was lazy to check if it's really the cause...)

anyway cache doesnt need accurate sleep, it's just to avoid eating up
all cpu while waiting for i/o. so simple usleep() would be better maybe?
(afair it was usleep() originally when i wrote it, maybe it was changed
later to ease portability?)

should be 0.001 or maybe 0.005, 5ms isn't noticable anyway and
the call overhead and inaccurate usleep may delay more than a few ms.

maybe backporting the new timing system from g2 would be a better idea...
