Or have the first hit after the expire set the expire time counter to the
next interval so the next hit does not even think to rebuild.  Then you can
also rebuild the cache to a temp name and overwrite the current cache when
it is complete.  This way to sleeping is required on long building pages
with many hits (they all just serve the old page until the new one
overwrites in an atomic write).
