But it calls accept-process-output, so it can still get stuck.  And even
if inhibit-quit is nil, maybe there's no frame open anywhere so the user
can't hit C-g.  So the only recourse would be connecting to it via
another emacsclient, which might fail to work if Emacs is stuck in an
accept-process-output waiting for a specific process.
