I am merging this into tumme.el right now. How about something simple
like using a defvar to store information about whether the clean-up
function has been called in this session or not?

After each call to `tumme-display-thumbs', check that variable, and if
nil, ask the user if it is OK to do a clean up (or really check if a
clean-up is necessary). We can provide options like "Yes, please
clen-up", "No, ask me later", or "No, and don't bother me again this
session" or something like that. Together with a custom variable that
determines if we should use cleaning at all, this should suit most
user's needs, right?

What do you say?
