Greetings, Takashi Yano!

>> This also causes gnu screen to freeze.

> GNU screen freeze without much of an effort under Cygwin.

>> To reproduce this:
>> (1) Start screen in mintty window.
>> (2) Detatch from the screen (Ctrl-A d).
>> (3) Login via ssh.
>> (4) Attach screen by 'screen -r' in ssh session.
>> (5) Detach from the screen (Ctrl-A d).
>> (6) screen freezes and is not terminated normally.

>> This does not occur if the user does not belong to
>> Administrators group.

>> I guess this is a problem of setuid codes.
