That was my fourth post to this list, I was referring to the other
three, particularly:

<http://mail-archives.apache.org/mod_mbox/subversion-dev/201003.mbox/%3C4BAA79DF.9040506@wikimedia.org%3E>

I could see that after being ignored on that issue, my only chance of
being heard would be to get to know the developers and then to take a
more personal approach. That's why I stayed on this list. Unfortunately
I haven't had much time to read it.

My problem is that Subversion is so slow, in terms of network
round-trips, that's it's virtually unusable in our application for tasks
like merging and annotating. Chia-liang Kao has done an awesome job of
providing a local cache layer for Subversion in first SVK and now
Pushmi. This would provide a good response to the many developers in our
community who are agitating for a switch to Git, except that due to a
minor deficit in Subversion itself, Pushmi is not usable for us. This
could be corrected with a patch to Subversion, possibly as short as a
few lines of code. I'm offerring to write the patch.

The Pushmi solution could then be documented on our wiki page on this topic:
