Wine able to replicate a high speed (e.g. 1 ms)
timer event where the called event routine chews
a lot of CPU. This is required because of the
bias some Linux kernel versions have against threads that
chew a lot of the CPU; this Sleep(0) yields enough
in that spin case doesn't trigger the bias.
Further, it should do no harm, but an fyi. */
