read /sys/doc/fs/fs.ps.  the worm is not a wayback machine, it is the
main storage!  however there is a coalescing period of 1 day where
changes are kept in the cache prior to being commited to worm.
the process of commiting changes to the worm is called the "dump".

so, for example, if i changed /rc/bin/P 10 days ago, the current
file tree would point to the same storage it did yesterday, and
both pointers would be into the worm.
