Hm, I suppose that could work. But it kind of destroys the "wc is self
contained" philosophy. The WC journals all of its actions, then
executes the journal. Our philosophy has always been that the
journal-commands refer to things strictly within the working copy.

Suppose you interrupt a WC operation, so that your WC is locked with
journals lying around. Then you let your WC sit around overnight.
During the night, a cron job cleans out /tmp. The next morning you run
'svn cleanup', which attempts to finish running the WC's journals... but
the journal refers to copying/moving a file in /tmp that is no longer
there. Whoops.

Oops, yeah, actually, I forgot about that detail. We *do* do a 'mv'
from .svn/tmp/ to .svn/text-base.
