Thread 27 is waiting on the "UpdateAsyncCanvasRenderer Lock".  It is not at all obvious to me why this monitor is reentrant, but that doesn't really matter here.

Thread 19 is the ImageBridgeChild thread and appears to be stuck in a GL call.

Thread 1 is shutting down and is waiting for the ImageBridgeChild thread to shut down.

The root cause presumably is thread 19 getting stuck in the GL call.  That causes the worker thread to wait on the ImageBridgeChild thread indefinitely and have the test timeout.  What I don't know is whether we're doing something wrong or whether this is some sort of driver issue (note this only happens on 10.6)
