And let us not forget that this inconvience is unexpected, gives Emacs
a bad name (since it sucks up CPU even when idle) and is
non-debuggable, since timer functions run with quit turned off.  It is
completely impossible for the average affected user (heck, it was even
for me until Richard gave me a direct pointer to stealth fontification
after a bug report of mine) to find out which of the thousands of
settings inside of Emacs is responsible for the problem.

So it is a bad idea for a default setting.

That would make it a good idea for a prominently accessible user
option.  I'd still think it a bad idea for a default setting.
