Thanks for the link.  I am using threads provided by the Lisp
implementation, and didn't want to deal with the possible quirks.

This is really neat.  It almost works now, except that Damage events
are not received when the window is passive, only when I click on it:
then the window gets an expose event and a damage event immediately
after.  Suggestions would be appreciated, I attached the C code.

Another thing: how can I disable the resizing of the window?
