Missing KeyRelease events from root window

[Daniel Brockman]

I believe some part of X (the server, Xlib, or something ---
I do not really understand how it all works together) drops
some key release events on the floor.

The following program demonstrates this (AFAICT) bug.

I get the following output:


weewam:~$ ./test
Try pressing `a', then pressing `b' (still holding `a'), then releasing `a',
and finally releasing `b'.  See if you get the final release event.

Then run this program with `--create-window' and try the same thing.

Press event for `a' (will process 20 more events).
Press event for `b' (will process 19 more events).
Release event for `a' (will process 18 more events).


weewam:~$ ./test --create-window
Try pressing `a', then pressing `b' (still holding `a'), then releasing `a',
and finally releasing `b'.  See if you get the final release event.

Press event for `a' (will process 20 more events).
Press event for `b' (will process 19 more events).
Release event for `a' (will process 18 more events).
Release event for `b' (will process 17 more events).


Notice that the final release event is missing in the first
run (i.e., when the program is watching the root window).

Hopefully I am just doing something wrong.

I am running ratpoison 1.4.0 (a tiling window manager), and
the following X stuff:


weewam:~$ X -version
