Concurrent access and "Delta source ended unexpectedly"

Hi

Looking through the code, subversion appears to lock the working copy
and the database, so working on the assumption that concurrent access
to a repository is supported, I tried testing using multiple clients
each in a separate working copy.

I have a couple of problems, one is that I can provoke deadlock
between the clients, the other is that I can provoke the following
error when trying to commit some changes:

  Sending wcstress.1617/bar2/foo1

  svn_error: #21006 : <Incomplete data>
    commit failed: wc locks have been removed.

  svn_error: #21006 : <Incomplete data>
    commit failed: while sending postfix text-deltas.

  svn_error: #21006 : <Incomplete data>
    Delta source ended unexpectedly

at which point the working copy seems to be broken.

My test is a script the invokes the Unix command line client, and it
works fine when I serialise the repository access. I am using
subversion revision 401, with apr, db and neon in the source tree, a
shared build and ra_local access.

Is it too early in development to expect concurrent access to work?

Is there anything special I need to do to enable concurrent access?

I will of course provide the script and instructions if this turns out
to be more than simply a configuration error on my part.
