That is why I suggested two separate sockets.

This would mean ordering was maintained only down to the socket level, no?

  Host host
    ControlPath ~/.ssh/ctlsock/%h.%Q
----------------------------------------------------------------------
  $ ssh host		# this creates ~/.ssh/ctlsock/host.lowdelay
  $ scp file host:	# this creates ~/.ssh/ctlsock/host.throughput

All subsequent bulk transfers will use the 'throughput' socket, and likewise for
interactive to 'lowdelay'.

Am I mistaken?
