I still think it is useful in the other contexts too.  YMMV.

It is ok to make this more configurable, but for 21.4 (feature
freeze!) we should limit this to a new compilation-highlight-duration
variable that can be set to one of the following values:

        0 => don't highlight
        N > 0 => highlight for N seconds (N may be float)

Any other value also means don't highlight.

The remaining question is whether the default should be 0 or 0.5
