No, I was assuming a persistent TCP socket & HTTP connection, but
the client waiting for the first response before sending the
second request, i.e. the classic RPC behaviour. Even the rather
primitive coast_upload.pl script, which is written in Perl and
uses the WWW::Curl::Easy library seems to reuse the same HTTP
connection between requests.
I haven't looked at the JOSM source code, but one way out could be
to start multiple threads, each having its own HTTP connection.
That would be a rather ugly (and possibly unethical) way to
over-consume server resources.
I haven't studied whether Java reuses the same connection, but my
proposed "bundle" operation would speed things up either way.

This sounds rather exotic. How many people have this?
