Maybe this is just nieve, but I always thought that it was the
responsibility of the party introducing the creeping feature to
underdatand and then minimize a potential performance impact.  But now
we're treading over ground brought up by John Dyson last week.

I've at least partially quantified the performance impact, which is
all I have time for.
