My idea for the hackathon was to add native 'svn list' support
to ra_serf. But that is not a release blocker.

If we broke something, it is likely one of the more complicated
cases where the need for manual intervention is not all that
surprising to the user.

ra_svn is certainly the ra layer that may benefit the most from LZ4.
Browsing through the code, I found a couple of TODOs that should
be simple to address this week.

I've got some ideas to enhance the protocol in 1.11 and that would
include using LZ4 for "mod_compress"-like full protocol compression.
However, those are non-trivial and are the one thing I like to discuss
with the people at the hackathon.

+1 on letting people gain experience with shelving.
+1 on marking the feature "experimental" in the UI b/c we might not
want to fully commit ourselves to upgradability. That is a departure
from the policy of previous releases.

Assuming no blockers come up, I think coming weekend would be
a reasonable value for $asap.
