Deadlock between main UI app thread and MILCore renderer thread


well it deadlocks between main UI app thread and renderer thread...

I attached the backtrace of relevant threads at the time of the deadlock.
NOTE: the console snippet from above and winedbg backtraces are from different
runs (different TIDs).

The interesting ones are: thread 0022 (UI thread) vs. thread 0033 (renderer
thread) I talked about in comment #2

thread 0022: 

Looks like the managed UI main app thread which synchronously waits for command
to be completed - signaled using event from renderer thread I think.

thread 0033:

The renderer thread. When the d3d9 device is created, the window handle created
by main UI thread is passed. The pixel format is propagated synchronously to
target window. Because the target (thread 0022) waits for event without pumping
messages it deadlocks.
