On Windows that would be certain breakage as the failed test count is still
above 100 (120 last Monday; 118 just now) As far as I can see mostly for the
single reason that Subversion keeps handles to .svn/wc.db open when the file
is deleted for removing the directory.
All subversion tests/actions that remove one or more working copy
directories just FAIL and there are a lot of tests and user scenarios that
add or remove directories.
This should be fixed before (or /really/ short after) switching to WC-NG as
the default working copy format. One solution would be to move everything to
the single working copy database, but I don't think you planned to do that
around this switch?

On Windows that number is much higher...
I would like to switch to WC-NG, but in the current state that is not an
option for me or any other Windows user :(
Summary of test results:
956 tests PASSED
43 tests SKIPPED
29 tests XFAILED (1 WORK-IN-PROGRESS)
118 tests FAILED
3 tests XPASSED (3 WORK-IN-PROGRESS)
