I agree with Kai.

Some days ago, Tramp got a patch checking for a dead process during
accept-process-output in order to react faster (in Tramp CVS, not
synced yet with Emacs CVS).

Despite of this and the outstanding solution for the auto-revert
problem: what else should be done? Tramp must wait for the output,
otherwise it cannot decide how to continue. And it doesn't know that
the output "obviously will never come".

Best regards, Michael.
