I considered extending stream_Demux to forward controls. Unfortunately, the
way stream_Demux works, this is most likely to cause deadlocks, at least if
the control request needs to return some kind of result. Namely, the
stream_demux thread could be waiting for data from the input thread
(callstack: pf_demux -> stream_Read), while the input thread would be
waiting for control results from the stream_demux thread (callstack:
pf_control -> stream_DemuxControl)
=> OOPS.

Yes.
