I'd suggest to also close the following issue:
* SVN-4557: ra_serf fails to delete directory containing many files
https://issues.apache.org/jira/browse/SVN-4557
The fix for this particular issue got in 1.9.4 and even though it's
not yet backported to the 1.8 branch, the described issue is fixed in
1.9 now.
