You can also add this to your fstab: shm /dev/shm tmpfs defaults 0 0
Then you can write whatever you want to /dev/shm (by default it will be 50% of your ram, its configurable). Then you can also use unionfs to enable the applications to write to your OS filesystem, while they will be really writing to /dev/shm (which is ram based). This requires patching the kernel.
