repository conversion success story

I'm just reporting cmpilato's results in converting our main svn
repository over to the new fs schema. It's meant to be inspiring to
others. :-)

* he patched r2092 with his undeltification patch [previously posted],
  made a static svnadmin binary of that, and ran 'svnadmin undeltify'
  on every 50th revision. That took about 5 minutes to complete.

* then he ran:

   svnadmin-2092b dump repo-bkp-2096 | svnadmin load newrepo

  This process took about 30 minutes to complete, and the two svnadmin
  processes (combined!) hovered around 30 megs of memory usage the
  whole way. Not too shabby.

* now he has a new repository. As mentioned before on the list, it
  has the nifty new feature of actually following copy history when
  you run 'svn log'.

* he's testing the repository today in many ways:

    1. run `svnlook info' on every revision of both the pre-converted
    and post-converted repository, and diff the two outputs.

    2. check out every Nth (N is not yet determined) revision of both
    repositories over ra_local and verify that we get the same tree in
    both cases.

    3. run phillip's concurrent access repos slammer(tm) script on
    the new filesystem.
