Not sure I follow: are you changing process-buffer of a process, or do
you have more than one process sharing the same process-buffer?  Or
something else?

I guess I don't know how to interpret "Tramp is instructed to use
another process buffer".  Who in this context is "Tramp", if there are
multiple async processes involved, each one with its own buffer?
