I have wondered for awhile about this code.

When the mmap file is growing, and one of the internal parts runs out of room,
what is the harm of throwing all the current work away, increasing the size of
this limit, and starting over?

Also, maybe the cache files should store some of these numbers inside
themselves(the above mentioned cache-limit).
