It can still be very useful: when you do M-x man RET pe TAB r TAB TAB
it will only run `man' once instead of 3 or more times.
That's the main purpose of the cache.  The fact that the cache is
preserved between runs of M-x man is probably more a misfeature, since
it means that the cache is never refreshed (i.e. gets out of date after
"aptitude upgrade").
