cool, so they've no real disavantage. Since sibilings pristine trees are
searched for I believe there's no need to replace pristine trees with
revlibs. However for the people not wanting to using hardlinks, revlibs
probably will work much faster than pristine trees (pristine trees can't
be hardlinked in such case). But if you use hardlinks likely you may
want to still take advantage of the more temporary property of the
pristine trees.
