ES should have no runtime cost other than some extra info for the
search phase. OTOH, enable/disable burns cycles (keystrokes aside
for a moment) no matter whether you hit some cancelation point
*with cancel request pending* or not. Well, there's a downside...
of course. It is just an additional/alternative tool, so to speak.

I'll really need a drink or two for some inspiration, I'm afraid.
