/bin/test is missing on both my CentOS and Ubuntu systems (on Ubuntu zsh
reports it's an internal command though):

% /bin/test -e /
zsh: no such file or directory: /bin/test

% which test
/usr/bin/test

I don't understand why this became a problem suddenly.  Weird.  I linked
/bin/test to /usr/bin/test but it doesn't fix the problem, it now
becomes the following, repeated many times:

14:08:05.762864 tramp-get-connection-property (7) # check-remote-echo nil
14:08:05.763021 tramp-get-connection-property (7) # check-remote-echo nil
14:08:05.763223 tramp-accept-process-output (10) # *tramp/ssh wd01* run
14:08:06.763572 tramp-accept-process-output (10) # 
tramp_exit_status 0
#$ 

Also did `with-timeout' fail or did we keep resending?  In the latter
case, I think we should show a count of retries and abort after 7 or so.
