tramp: Waiting for remote host to process data... twenty minutes

[ken]

Using tramp is great, but it's hanging twenty minutes or more on the
message, "Waiting for remote host to process data..."

This happens when I C-x C-s or when an autosave happens.  It might be
happening at other times too... I don't know how to know this.

I've not been able to find any problem with the networking between the
two machines.  Both machines are able to ping each other.  In fact, I've
had an ssh session during the entire tramp session and there's no delay
at all with ssh.

*tramp output* is empty and has been during the entire session.

So is/has been *tramp/ssh ken@my.home.net*

Here's some of the *Messages* output (blank lines inserted to avoid
auto-wrapping mess):

Here's *debug tramp/ssh*, or just the last part of it.  It's a large
file, more than 1.3M, large parts of which appear to be random
characters following a line stating: "# Sending data to remote host..."

Don't know which part of this is important so I saved the whole thing
but am including here only the last several lines:

--------------- snip -------------------
# Sending end of data token...
$ EOF

$ echo are you awake

tramp_exit_status 0
