Okay, I have a fix for multiple monitors syndrome, and I think I've
isolated the backingstore problem for long running processes (it wasn't
where I thought).  I've been unable to use the CVS all night (connection
refused) -- don't know if others are having problems (might be on my
end).

For the BackingStore thing, it looks like the problem is in calls like
Get_location_with_pointer() and such, as these functions seem to use
blocking calls.  I did a little experiment, and it bears out this
conclusion (debugging is a pain with detached processes...).  Anyway,
I'll try to work up a solution (the test fix I did sucks CPU cycles...).
