The fundamental problem here is that there is a big data structure
(the archive) that needs to be constructed (by fingerprinting the
whole replica, file by file) and saved on the disk, on each replica.
What would help matters would be if the update detection phase (which
builds the archive) were able to work incrementally -- computing a
little, saving a checkpoint, computing some more, etc. This would not
be impossible to do, but it would take some work -- you'd have to be
able to interrupt the depth-first scan of the filesystem in the
middle, escape back up to the top level, write the file, and start
over (but not redo too much work); also, on startup you'd have to
