Re: svn.collab.net repos failures.

Wow, we're definitely closing in on this one! I can reproduce the
wedge bug with 0.28 HEAD, but not at all with 0.27. (I believe Karl
just reproduced the wedge *exactly* as I did.)

Here are the details:

0.27 experiment: using svn's own repository (HEAD=6900, format=1)

* no hangs for 3 simultaneous checkouts
* definitely faster checkout speed.
* minimal memory usage: each svn client at 3M, httpd at 2M
* accidentally checked out root of repos, had to sigkill the svn clients.
  after killing the clients:

   - repository is not wedged
   - httpd is still at 94% CPU, however (!)

0.28 experiment: using svn's own repository (HEAD=6917, format=2)

* 3 simultaneous checkouts caused repos wedge after 40 seconds or so:

     - error_log says: "db OOM" error, and 30 seconds later,
       "db runrecovery" error.

     - access_log says: 500 response when doing a GET of
       project_nav.html. timestamp matches the 'db runrecovery' error.
