This reverts commit 4617f83f.

The assumption that GetTickCount() gets updated after Sleep(1) holds only
when there is no other software running on the system. If any program uses
timeBeginPeriod() with values 1-15 then this assumption breaks.

A lot of common user software calls timeBeginPeriod() - this includes browsers,
media players, voice communicators, IDEs and store fronts.
