Owen had a suggestion for how to do this, and Anders did an
implementation:

        http://andersca.org/patches/icon-theme-cache.diff

I haven't looked at it though, so I don't know the status of
it. 

For fonts basically the same approach would work. Basically make sure
the fc-cache-1 files can be mapped and used directly instead
allocating memory for what is essentially just a representation of the
cache.
