Come on! that's _got_ to be an exaggeration!  Otherwise, how come 
overlays were used since their introduction in Emacs 19, on machines that 
are much slower than what we have today, and no one ever said they were 
useless?

Perhaps they were not designed for having thousands of them, after all?

Please suggest a better implementation, then.  It's not useful to argue 
about whether the current one is bad or not unless we have an alternative 
to consider.
