Subject: Lock draw_queue id to prevent race conditions
X-Git-Url: http://pileus.org/git/?a=commitdiff_plain;h=8941c8e6e06588d43732645e6af3feb959f1eb41;hp=8941c8e6e06588d43732645e6af3feb959f1eb41;p=grits

Lock draw_queue id to prevent race conditions

On Windows, the main loop runs right after the idle source is added.
This causes the callback queue_draw function to assign a dead ID which
leads to the viewer never refreshing.
