	Actually, even with complete checkouts subversion can be fairly
forgiving.  I just tried creating a test fsfs backed repository, checked
in a few revisions, then started deleting revision files.  "svn log"
failed right away, but checkouts kept working for a while, until I
removed a revision that contained changed needed to build the checked out
view.  Any time there's a "large enough" change to a file future revisions
won't need the earlier ones.
	However, when a critical file does get lost it doesn't seem like
the easist thing in the world to recover.  Some parts of a revision
file are text, but the contents of stored files are not, so a recovery
program would need to be written.
