While looking through the various 1.10-related topics, I remembered about
this issue.  I have been able to narrow it down in my environment to (Ensure that even long-lived DAV
connections use up-to-date authz.)

Perhaps, a simpler reproduction script would be to issue an 'svn log' for
a medium-sized repository.  In my environment, doing so for the trunk of
TortoiseSVN's repository with 25,000 revisions causes the httpd process
to consume up to a 1 GB of RAM while processing the request.  Overall,
the log takes around 11 seconds instead of 2, compared to 1.9.7.

Unless I am missing something, this might be worth considering before the
1.10 GA release.
