  I was going to say "use a recent snapshot because the 'Broken Pipe' 
problems were fixed by the Gold-Star deserving Pierre"... BUT I tried your 
testcase and it fails (intermittently) even with the latest snapshot 
(20040928).
  Pierre's patch DID fix the broken pipe issues I reported so this might be 
a different problem.
