Issue 2180: Noise and system slow-down due to timeBeginPeriod abuse
http://code.google.com/p/chromium/issues/detail?id=2180
New issue report by rustamabd:
Product Version : 0.2.149.29 (1798)
Other browsers tested:
Add OK or FAIL after other browsers where you have tested this issue:
Safari 3: OK
Firefox 3: OK
IE 7: OK
What steps will reproduce the problem?
1. Get an old laptop
2. Start Chromium
3. Notice degraded system performance and (sometimes) excessive noise when
running on batteries
The Problem
Chromium calls timeBeginPeriod(1) which has a global effect on the system
scheduler. Per Microsoft, changing the resolution of the timer for a
prolonged period of time is a bad thing to do:

I propose to remove calls to timeBeginPeriod and timeEndPeriod. This will
decrease accuracy of the timer from 1ms to ~20ms. As an alternative, use
another high-precision timer function, QueryPerformanceCounter.
