I'm not positive, but I'm pretty sure the sleep command in linux does
not behave the same way it does in windows.
As you know, in windows, a sleep command (even if delivered with a
parameter of 0) gives up time slices to other programs on the system.
This does not appear to be the case on linux.
On linux, the sleep command simply suspends the process for the
specified amount of time, but so far as I can tell, does nothing for
unused cpu cycles.
This is what "suspend" means, that process doesn't compete for cycles,
so they go to the other processes. Since the sleep is a kernel call, I
can't really imagine why this would not be the case.
So my guess something else is spinning (e.g. in a thread).
