Sorry about that, didn't have xcb-xkb enabled (didn't realize I had to
explicitly enable it in xcb).  With the xkb event it works fine.  And
I guess the above is another hint to what might broken: initially Alt
works, but Alt-tabbing away breaks it so that Alt never triggers
again... so it's the opposite of what we had before...
