I think the relevant code is in keyboard.c in the POLL_FOR_INPUT
conditional blocks. Currently this code handles detection of C-g
according to the comments, I do not know why it manages to do that
without also handling general detection of input.

I don't know if this code is only used on Windows, or other systems
also use it (maybe old versions of X?). It doesn't appear to have
been written specifically for Windows.
