Blocking with an even will sleep until someone wakes you up, it's very

We were talking about the overhead of a "sleep for n milliseconds"
functionality itself, and not about waiting for some event.
Abusing it for polling of course is not what sleep is meant for.
Sleep is for granting the CPU for other processes for (at least) a
predefined time.
See the mail of the original poster: this is what he asked for.
