- With NT, you can have multiple threads per process and multiple windows
- per process. Am I correct in assuming you can have at most one thread
- issuing WIN32 calls per window?

- From perusing the docs, this does not seem to be exactly correct. Each
- thread which owns windows (having started them) has its own message queue,
- thus it will read the messages. However, any thread seems to be able to do
- Win32 window output operations on any handle, even if the thread is not the
- one that created the window. Seems like the rule is: Have a handle --> able
- to do output.
