I'm working on a performance visualization package and I would like to
give the user the option of displaying views on multiple screens. The
problem comes when trying to wait for events from the different
windows. If the windows are handled by different display servers, the
event wait loop turns into a spin-loop since there is no way to do a
blocking request for events from multiple servers (right???).

The only other solution I could see is to "fool" a display server into
believing that another, remote, display, is really just another screen
of this display. Has anyone toyed with this idea before? Would such an
extension fit into the exiting generic display server code elegantly?

Has anyone else come up with an interesting (and efficient) solution
to this problem?
