Hi Chris et al., trunk should definitely be better in this respect.  =20
We now use a pipelined 10 connection pool instead of negotiating a new =20=

connection for each request.  We do need to fix a bug in trunk (just =20
filed a patch) that is causing connections to be closed far too =20
frequently, though, so you may see lots of connection_closed errors in =20=

the logs if you try it now.  Best,
