The "correct" solution would be to control zapping through xkb rulesets.
Currently, the default symbols include the action Terminate_Server on
Backspace. Removing this sym from the defaults and providing it through an xkb
option allows C-A-B to be activated at runtime. It also means you can remap
zapping to whatever key combo needed.

The patches required for this are:
- xkeyboard-config needs to remove Terminate_Server from the default symbols
  and provide it through a set of options.
- the server needs to re-enable zapping and require the xk-c release.

This is not particularly high on my TODO list, but feel free to submit
patches. Note that xkb had a major cleanup since server 1.6. I encourage you
to work against git master if you want to get this change in.
