Ah - cool, I missed the part about passing in NULL.

Note, that all Ruby threads really run in the same operating
system thread.  This means if you call an operating system
function that blocks, all of your ruby threads will wait until
it returns.  This can sometimes make things challenging; but
for what you're doing I don't think it will be an issue.

Sounds like you can call RegisterHotKey() ... then start calling
either PeekMessage() or GetMessage() and watch for your WM_HOTKEY
messages.
