Yes. After screen creates the socket for a new session, it should check
whether the permissions it tried to set really got set, and if they didn't,
warn the user that s/he won't be able to reattach. Then when it tries to
reattach, if it won't because the permissions are too loose, it should tell
the user that instead of just saying "There is no screen to be resumed."
Maybe it could even provide a way to forcibly override the permission
check, and let the user connect insecurely if they want to.
I'll work on this whenever I have a spare hour or two. Meamwhile, I'll put
a warning about it into README.Cygwin.

Yay! I love a problem solved. Happy screen-ing.
