RE: Multiplexing

Whoops, I'm scatterbrained today.

This is certainly true for server-side multiplexing.

Client-side multiplexing is a much trickier proposition.  We use cookies,
setTimeout(), and window.open() to share JavaScript object references
between windows.  There is a slightly broken leader election protocol
to decide which window holds the persistent connection at any given time.
If all goes well, persistent connection migrates automatically when
windows are closed or new windows are opened.
