Compositor gets stuck if a sequencer window is also visible

Description

--- Operating System, Graphics card ---
Linux Mint 14, 64bit, Nvidia GTX 460

--- Blender version with error, and version that worked ---
Error appears on manual git build, buildbot build and 2.65a official release

Error:
If while using the node compositor there is also a sequencer preview area visible, the compositor will get stuck with compositing while trying to update on node changes.

In the sample.blend simply play around with the Curves node. The Image backdrop image will only be partially on changes as long as the sequencer preview area is visible. The Problem gets more intensive with more complex nodes like blur with a big radius and disappears as soon as the top right area is changed to another type.

Compositor now should work fine when sequencer is used in OpenGL preview. But sequencer will still kill compositor job when sequencer uses rendered preview and there's currently no way to solve this because of internal design issues of sequencer..

Thanks for the report to, considering it's fixed since ogl render will work fine now :)
