fixing dcss server watch script for console (ipcs)

gistfile1.txt

run:

$ ipcs -m 

and it should list a key owned by crawl. should be something like 0x12345678

example:
------ Shared Memory Segments --------
key shmid owner perms bytes nattch status
0x52147880 0 crawl 644 33648 1

note the key and run ipcrm and pass the key (as root)
$ ipcrm -M 0x52147880

that should make new dgamelaunch instances work.
they might not be able to see everything that happens in the old games, but at least it won't hang.

(I don't recall what the shm segment is used for exactly; I don't look at the dgamelaunch code much)
