I'll put together something better this weekend and include it in the
source, as well as posting it to the list. Briefly, there's always a
line of signature identifying the machine and pointing to the next
block. Then you have an FcCache data structure written in binary
format, followed by a chunk of memory which gets mmapped. On a global
cache, you have a number of these dir chunks, prefaced by directory name.
