shared memory. the kernel uses it for IPC communicatins and other socket type 
things. You can use it for temporary places too.. it's a ramdisk (kinda).
I currently do this on the mothership:
mkdir -p /dev/shm/tmp /dev/shm/var/lock /dev/shm/var/run
mount --bind /dev/shm/tmp /tmp
mount --bind /dev/shm/var/lock /var/lock
mount --bind /dev/shm/var/run /var/run

this makes /tmp, /var/lock, /var/run all ramdisks , amazingly fast, and they 
clean themselves out when you reboot. also, they don't take up an disk space
