screen attached but no screen process running

[Dr Bean]

I occasionally get this problem:

        address@hidden greg]$ screen -ls
        There is a screen on:
                25124.pts-312.momotaro  (Attached)
        1 Socket in /tmp/uscreens/S-greg.

        address@hidden greg]$ screen -d

And my attempt to detach the screen hangs. And if I kill that
attempt to detach the screen, then I see that there is no screen
process running:

        address@hidden greg]# ps aux | grep screen
        greg     14309  0.0  0.6  5540  872 pts/481  S    15:24   0:00
        screen -d
        root     14314  0.0  0.4  5396  600 pts/482  S    15:25   0:00
        grep screen
        address@hidden greg]# /bin/kill -s SIGQUIT 14309
        address@hidden greg]# ps aux | grep screen
        root     14317  0.0  0.4  5216  580 pts/482  R    15:25   0:00
        grep screen

But the screen is still attached:

        Quit
        address@hidden greg]$ screen -ls
        There is a screen on:
                25124.pts-312.momotaro  (Attached)
        1 Socket in /tmp/uscreens/S-greg.

I seem to have this problem when I make a fingering mistake, but
perhaps that is a misperception.

Is it OK to try deleting:

address@hidden greg]$ ls -al /tmp/uscreens/S-greg/25124.pts-312.momotaro
prwx------  1 greg greg 0 Mar 10 13:19 
/tmp/uscreens/S-greg/25124.pts-312.momotaro
address@hidden greg]$
