While I'm not quite sure of the rhyme or reason, what's occuring is that
CVS is creating a mirror directory layout of the subtree you're operating
on in /tmp.  This means you'll actually likely run out of inodes before
space, FWIW.  I usually set TMPDIR to point it at /usr/tmp to avoid this
being a problem.
