Hmmm, this seems to put the HTTP application into a hopeless situation -
not to mux, you get the head-of-line blocking problem that is
practically harmful towards the web users' experience; to mux, you get
the theoretical "harmful layered mux problems" (towards the network
bandwidth efficiency, I guess) :-)
