As I said before, I suspect your numbers would be much lower if I wasn't
sending HEAD requests for each file. Unfortunately, ra_serf is depending on
the ordering of the pipelined requests (PROPFIND results for a given path
must be processed before the contents of the file are fetched), and I don't
know how to make that happen without ripping apart the pipelining machinery
and doing something custom there.
