Hi,
         On my UP PII, the kernel complains a lot:

Unlink of SHM id 7897329 failed (-13).
Unlink of SHM id 7930098 failed (-13).
Unlink of SHM id 7078104 failed (-13).
Unlink of SHM id 7110873 failed (-13).
Unlink of SHM id 7143642 failed (-13).
Unlink of SHM id 7176411 failed (-13).
Unlink of SHM id 7209180 failed (-13).
Unlink of SHM id 7241949 failed (-13).
Unlink of SHM id 7274718 failed (-13).
Unlink of SHM id 7307487 failed (-13).
Unlink of SHM id 7405794 failed (-13).

Unlink of SHM id 7536870 failed (-13).
Unlink of SHM id 7569639 failed (-13).
Unlink of SHM id 7602408 failed (-13).
Unlink of SHM id 7635177 failed (-13).
Unlink of SHM id 7667946 failed (-13).
Unlink of SHM id 7700715 failed (-13).
Unlink of SHM id 7733484 failed (-13).
etc, etc.

It seems to work OK though (uptime 12minutes). Quake works. I've got a
lot of memory.

The fixes that I have used are
 1. put dget around BOTH arguments to lookup_one in ipc/shm.c
 2. revert move of task_lock in exit.c
