Console

I can confirm that this is a issue on Windows 7. When trying to run Git
within Console2, I can only issue a few commands before it freezes up. The
other tabs remain functional.

There seems to be some issue in message passing from CMessageLoop to
ConsoleHandler::MonitorThread. I am able to repro it consistently with:
1. Open console version of vim with a long file
2. Keep the down arrow key pressed for few seconds
3. Console2 doesn't respond, however other tabs respond

This sends bunch of WMKEYDOWN events to the app, but they seem to get lost
in the thread's message queue. MonitorThread enters an infinite loop
waiting for events to occur.

Let me know if a dump or callstack can help.
