by the way, I wanted to do a little profiling and I ran the demo CoD4 
against the head (from Sept 10th) with the csmt patches. It crashed a 
few times, but sometimes it didn't. I put my server call logging / 
debug-toggle patch in and this is a sample from starting the game until 
the level is finished loading (minus things called less often)

3171    enum_key
5512    send_hardware_message
5682    get_window_children_from_point
5709    accept_hardware_message
8657    read_process_memory
8712    open_key
9441    close_handle
10296   get_key_value
86708   get_thread_input
202405  get_message
245653  set_cursor
553083  event_op
640397  release_mutex
1468300 select

And this is a sample of several minutes of game play (I died a lot)

2457    get_window_property
7551    get_key_state
11958   get_window_children_from_point
17232   accept_hardware_message
19087   send_hardware_message
19780   get_thread_input
32922   set_cursor
41224   get_message
638672  event_op
2282578 release_mutex
3246029 select

There was still a lot of graphic artifacts in game play (I have an 
nvidia card, so I always suspect their drivers).
