I've used the recipe for "direct-async-processes" as suggested:
(add-to-list 'tramp-connection-properties
(list (regexp-quote "/ssh:user@host:")
"direct-async-process" t))
and at first (the connection was already open) it didn't take
effect. I think I had to kill the connection buffer for the new
property to be used. Would be nice if this was instant.
But also, after that I tried altering tramp-connection-properties back
to disable direct-async-process for that host (for the purposes of
testing and measuring things more precisely), and found that changing
the variable doesn't bring the new behavior back. Restarting Emacs
didn't bring the old (non-direct) behavior back either - I had to edit
the ~/.emacs.d/tramp file by hand to remove that property.
I think that's something that might confuse other users.
If you want to remove a property from the cache, you need to call one of
the tramp-cleanup* commands. See (info "(tramp) Cleanup remote connections")
