Oh, I never said we don't have problems.

This one should be solved at the source, though (fixing the package so 
that the mode-line redisplays faster). Or perhaps by disallowing :eval - 
if that is at all feasible.

But I suppose throttling mode-line display should help with wayward 
customizations (which is good, of course, all other things equal).
