Well, I sent the patch to zhakov and included a list of failing tests.
I thought that they were caused by out-of-order processing, but I've
added code to sort the adm's back into queue order before running
Unfortunately, I'm getting the same list of failures...

Yea, we already keep all that data in memory during
svn_client_commit4(), so I did this to keep down the added size of the
constant factor to O(n)...

No idea, but I'd say the added overhead should be negligeable w.r.t.
the amount of i/o in the post-commit processing.

That's your mailer :-)

Ok. I tried to make it more clear, but given that there are still
failing tests, I don't expect to commit it yet anyway.
Revised patch attached. Still failing these tests:
FAIL: schedule_tests.py 10: status after add of deleted directory
FAIL: copy_tests.py 8: copy a tree and delete part of it before commit
FAIL: copy_tests.py 24: wc to wc copy with deleted=true items
FAIL: copy_tests.py 41: move a file twice within a moved dir
FAIL: copy_tests.py 42: move a file out of a moved dir
FAIL: copy_tests.py 43: move a dir twice within a moved dir
FAIL: copy_tests.py 44: move a dir out of a moved dir
FAIL: svnlook_tests.py 2: delete file in moved dir
