Can't queue 'em.
Scenario:
file-exist-p -> Tramp -> accept-process-output
<<Now process filters and sentinels and timers can be run>>
One of those async thingies calls
file-readable-p -> Tramp -> ????
If it's on the same connection Tramp is stuck: its connection is either
busy waiting for some answer from the remote host (which is OK: we can
wait) or busy waiting for accept-process-output to return so Emacs can
react to the remote process's output; but accept-process-output can't return
before file-readable-p is finished. Sending new commands to perform
file-readable-p canbe tricky because the remote shell might be in any
intermediate state, so we'd need to detect this state, save it and restore
it when done. Or else open up a new connection.
Note that the above also shows that async code is not only run when you call
accept-process-output or sit-for or sleep-for or read-kbd-sequence: it can
also be run when you call file-exists-p. I.e.
(let ((default-directory "/a"))
(if (file-exists-p default-directory) default-directory))
can return "/b" (if one of the process filters changes default-directory).
