please stop repeating this nonsense.  there are no "process time timers" in con-
temporary operating systems; only tick counters.

there are patches for linux and commercial add-ons to most platforms that lets
you use hardware performance counters for process stuff, but there's no way to
emulate that by playing with different existing Unix or Win32 API:s; the thing
you think you're using simply isn't there.
