Bug Description
SRU Justification:
Impact: When multiple DRI applications are running on an i965, and the screen goes into standby, one of the applications will sometimes hang when the screen is woken back up. Sometimes this occurs with compiz, which renders the desktop unusable. In at least one case, the hang was in DRI2GetBuffersW
Fix: Bisected e8e7a2b8ccfdae0
Testcase: While using Unity, run "glxgears &" and "xset s 1". Continue to wake up the screen when it goes into standby. On affected hardware, either glxgears or compiz (i.e. the whole desktop) will eventually hang
