Digging into that functionality would seem to be necessary if I were
trying to stop events from my div from propogating to the map.
OpenLayers.Popup does this - registering itself on a number of events,
preventing the underlying map from seeing them when the event happened
in the popup.

What I'm looking for is quite a bit simpler, if somewhat more drastic.
I don't want the map to respond to input at all, until I let things go
again.  A simple kludge is to add a boolean idle:false to
OpenLayers.Events, then to add 'if (this.idle) return;' to the beginning
of OpenLayers.Events.TriggerEvents().

Then, between if I set map.events.idle = true, when I display my div,
and set it to false when I bring it down, the map will respond to
nothing while my div is visible - making it act like a modal dialog.
