hmm - some of it is interesting.  But after applying the change, it's still not
working properly for me.  So my patch tonight reverts the (relatively small)
change from early 2010 which is the basic issue, and we can pick apart this

Generally what I saw: the display in test/ncurses in response to mouse-4
(wheel-mouse-up) is clearing parts of the lines.  The "*" expected to show
in response to mouse movement for TERM=xterm-1003 is not showing (most of
the response lines are blank).  Reading through the changes, it seems that
you might still be assuming that detail about 64 vs 96 is incorrect.  But
I'm testing with xterm in the modes that the wheel mouse and any-event
logic are designed for...

However, the queue-draining aspect is related to the change I'm temporarily
reverting.  So that's an area to explore.

I think that if I can guide you toward setting up the same testcases,
then the integration process will go smoother.  It would also help if
the patch were refactored into several phases, each of which would make
some specific improvement that could be tested.
