Bug 848481 - ♫ Don't say ClientWaitSync unless FOREVER ♫ - r=jgilbert

This fixes a flickering bug with some NVIDIA drivers. From the comment:

Wait FOREVER, primarily because some NVIDIA (at least Tegra) drivers
have ClientWaitSync returning immediately if the timeout delay is anything
else than FOREVER.

FIXME: should we try to use a finite timeout delay where possible?
