How to Unpause Applications in Mac OS X

I asked this question on Superuser.com after experiencing this problem. Now it’s accessible to everyone.

When something goes wrong and you run out of memory on Mac OS X, the system puts your existing applications to pause to prevent the system from becoming unstable. After taking care of the problem and freeing more memory, you might notice that the applications you had are still frozen. To unpause them, find their PID using ps and use the kill command to revive it (irony)

kill -CONT 111

Of course, 111 here is replaced with the PID you found with ps
