    Yes, I know of at least 2 causes:
    - it's based on polling and may take a long time before the next poll
    - the stealth-fontification causes swapping, and so even if the poll comes
      immediately, pages need to be swapped back in before the user's command
      can complete.

I see.

The motive for stealth fontification was to avoid delays when moving to
another part of the file.  Is fontification now sufficiently fast
that such delays are not much of an annoyance any more?
