What exactly do you mean by sleep?
If it's an asynchronous, surrender-the-CPU-while-I-take-a-nap thing, then
it's probably a few microseconds. If it's a busy-wait loop and if you're
using a Pentium-type CPU, there's a built-in register that measures CPU
clock ticks. With a 500 MHz clock, the RDTSC instruction returns the time
in 2 nSec units using a 64-bit word.
