If you want another data point, on my 2017 MacBook Pro visiting xdisp.c
took 1:30 min of background work (using 25% of the CPU).
Is it possible to make the feature optional, even for the default
font-lock decoration level in CC mode? So only the people that want
more accurate highlighting of types pay the cost of this background
work.
