I think this may be the result of a bug that was reported a month or two
ago.  Lynx wasn't always closing aborted connections, with the probable result
that the proxy stalls waiting for its output to be consumed, whereas 
the CERN proxy or a suitably configured Squid will complete the transfer in
the background if the connection closes.  I think the bug was being 
detected as the result of the file descriptor leak.

There is no official protocol for signalling caches to go into background
mode.
