<p>
On Windows, Go programs in Go 1.5 and earlier forced
the global Windows timer resolution to 1ms at startup
by calling <code>timeBeginPeriod(1)</code>.
Go no longer needs this for good scheduler performance,
and changing the global timer resolution caused problems on some systems,
so the call has been removed.
