   That's definitely a bug. It would be great if you could produce a
   backtrace, and if you could provide involved Tramp buffers.

Here is a backtrace for the hang (the usual behavior).  I will give a
backtace for the error if I can still reproduce it.  It happens
infrequently.  There _always_ is either a hang or an error however.
The Tramp debug buffer gets messed up by printing auto-revert related
stuff every five seconds.
