Here setxkbmap doesn't cause any XCB_XKB_NEW_KEYBOARD_NOTIFY events, only
XCB_XKB_MAP_NOTIFY. I tried this with Xwayland though, maybe that behaves
differently...

It's probably fixable somewhere in either setxkbmap/xkb or the X server, but a
compression timer would work even with older versions and also for other
causes like xmodmap, which can be much worse than just 15 events.
