This sounds fragile to me. For one thing, the kernel may not use ITC
at all for timeouts (true for most NUMA platforms). Also, even if the
ITC is in use, you'd probably have to resync them on the slave CPUs
after restoring the time-keeper's ITC value. Not to mention that if
the timeout is related to an external event, then faking time won't
help no matter what.
