While I was strongly against making ra_serf as default in svn 1.7, I
don't remember that I suggested to reinstate ra_neon.

I believe that most of the issues comes from the skelta mode (XML
report with many PROPFINDs/GETs) update editor implementation in
ra_serf.

So compromise solution is to implement non-skelta mode in ra_serf and
make it default in svn 1.8. In this case some issues will be solved
automatically. Like:
* handling events on each open connection regularly.
* handling "408 Request Time-out" responses
* growth of server logs, expanded number of server connections

We already reduced number of requests for 1.8 servers, so may be we
can choose to use "skelta mode" for 1.8 servers and non-skelta
(ra_neon style) for pre-1.8 servers?
