Absolutely. Like with any similar interaction in
Emacs the delay before starting should be a user
option. Users are different, and user machines etc.
are different.
Another possibility is for the option value to be
a choice of either:
* A non-negative number of seconds (or maybe natnump)
* A cons (SIZE . DELAY), where SIZE is the buffer-size
threshold: no delay if the buffer is no larger than
this, and DELAY seconds delay if greater than this.
Another possibility, to accomplish the same thing (delay
and threshold) is to have two different options:
lazy-highlight-delay - just the delay
lazy-highlight-threshold - just the size threshold
The latter approach is what I use in Icicles, for
several such settings, e.g.
`icicle-incremental-completion-delay' and
`icicle-incremental-completion-threshold'
But maybe the former approach is simpler.
