Re: screen refusing to reattach

Okay, this just happened to me again, and Jeremy's suggestion didn't do the 
trick.  I thought I'd take a moment while this was fresh in my mind to 
describe ANAICT the exact sequence of events.

1) The window I'm currently working in locks up.  On this particular occasion 
I had been away from the term, but only for a minute or so.

2) I can switch to other windows and they appear to be responding correctly.

3) I return to the locked up window and kill it.  I get the "do you really 
want to kill this window prompt".  I hit 'y'.  The window disappears, but then 
screen is locked (with the "do you really" prompt still there).  "Locked" in 
this case means no key appears to do anything.

4) I kill the term.

5) In a new term, I check the processes.  I have one screen -s running in an 
Eterm (that's on the base machine), two screen -x's running in -tcsh's (from 
who knows where), and one orphaned screen -x (presumably the one I was just 
running here on my off-site machine).  (That's not including the screen 
processes related to my completely separate screen session, which is never 
impacted by the first session crashing horribly.)  Oh, and also of course one 
SCREEN.

6) I kill the orphan screen -x first, then kill the -tcsh's that are parenting 
the other screen -x's, then kill the freshly orphaned screen -x's.  The 
-tcsh's require kill -9's (typical for a login shell IME), but the screen 
processes go nicely.

7) Try to reconnect with screen -x, no go.  Now kill the Eterm and the screen 
-s as well.  Try screen -x, screen -d, screen -D, and screen -DD; all just 
hang (but respond to Ctrl-C).  A screen -ls shows the session is "attached".

8) Sighly dramatically, kill -9 the SCREEN.  This removes the session from 
screen -ls and I can start fresh with a new screen -s.

So does anyone have any thoughts on why this occurs and how to stop it?
