I'm afraid I don't understand you: Do you mean that just the last
step is too complicated, or that the whole procedure that I described
is too complicated?
At some point, I thought I understood what you were suggesting, but
now I'm not sure anymore.
Let me try to describe my understanding with less detail, then please
tell me if I got it at least at this level.
Whenever Tramp is invoked, it looks to see if the connection
buffer is busy. If it is, it knows that Tramp is interrupting
itself, so to speak.
If this is the case (Tramp is interrupting itself), Tramp "takes
over" the command in progress, fetches all output from it and
stashes it someplace safe.
Then it does its own thing.
Afterwards, it gets the output from the safe place, inserts it
into the connection buffer, and makes it appear to the
"interrupted" "master" Tramp as if nothing had happened in the
meantime.
You were also talking about a queue of commands, which I'm not seeing.
So this would be an indication that I misunderstood you.
(The above does imply a stack of commands, corresponding to
interruptions of interruptions.)

Hm. If more than one thread of execution will be woken up at the
same time, then surely the above procedure won't work.

Maybe once I understand your proposal I will understand that it is
less fragile...
