No, they're not.  Tom says some add-on tools use 'em.  I think they 
should be removed, and we should cache patches properly somewhere else.

Not worth it.  If you have a revlib for patch-16, all it gets you is the 
 ability to build patch-15.  The win isn't worth the work or messing up 
the code.

Using archives to store the cache instead would avoid messing up the 
architecture.  Well, I suppose you could devise an "archive" whose 
underlying implementation was a revlib.
