Fair enough.

I took the 1.6.x branch and ran the test suite. It produced about 950
working copies, and the (compressed) tarball sits at about 850k. I'm
thinking about recording 'svn status' for each working copy, and
checking the tarball in as test data. We can then run an 'svn upgrade'
on each working copy, then 'svn status', and verify that the two
status results match. (caveat minor improvements in state tracking and
status reporting)

But... running upgrade on about 950 working copies and checking their
status isn't cheap. The tarball sizes don't bother me too much... I'm
more concerned about test suite runtime.

Anybody else? Should this be "normal test run"? Or should we set up an
"extended" set of tests and drop this into that batch?

Or not even go with this approach?
