Great work indeed.

The code seems to consist of the intensive use of inline assembly and
thread manipulations.
I guess it will not work for ruby 1.9.x 64bit version.
And it has some superfluous overheads in thread handling and sleeping delay.

Anyway, I expect it will work on ruby 1.8.6 in most cases.
But, here are some issue.

W32Thunk.call('user32','MessageBeep',1,-1) failed with the message
./w32thunk.rb:146:in `_start_call': strtoul("-1", ...) failed (fatal)
        from ./w32thunk.rb:146:in `call'

This callback test blocks on GetWindowTextA calling.
call = W32Thunk.callback {|handle,param|
	buf = 0.chr * 200
	W32Thunk.call('user32','GetWindowTextA',1,handle,buf,200)
	buf.index(param).nil? ? 1 : 0
}
W32Thunk.call('user32','EnumWindows',1,call,'UEDIT32')
