Re: emacs hangs at occasions using tramp + opensshd(cygwin)

[William Xu]

Enter your bug report in this message, including as much detail as you
possibly can about the problem, what you did to cause it and what the
local and remote machines are.

If you can give a simple set of instructions to make this bug happen
reliably, please include those.  Thank you for helping kill bugs in
TRAMP.

Another useful thing to do is to put (setq tramp-debug-buffer t) in
the ~/.emacs file and to repeat the bug.  Then, include the contents
of the *tramp/foo* buffer and the *debug tramp/foo* buffer in your bug
report.

--bug report follows this line--

I managed to get all the following through `emacsclient -e'.  One
interesting thing is that when I run tramp-submit-bug from emacsclient,
the emacs server will allow me to write title in the minibuffer, select
the y-or-n-p question, and after that, it refuses any key inputs again...

When emacs hangs: 

,----[ minibuffer ]
| trmap: file attributes with perl: /ssh:/.../
`----

The following is the tramp debug buffer, IIUC? 

,----[ "*tramp/ssh address@hidden" ] 
| (nil 1 1003 513 (18418 5134) (18417 61710) (18417 61710) 2806 33216 t (0 .
