Yes, and my yugo gets bad gas mileage when I'm dragging a piano around
behind it. What's your point?

Why are you creating the shared memory object in a loop?

Also, the key is supposed to be an integer or a 4 character string, not
a file name.

Finally, why are using shared memory when you don't seem to be sharing any
memory?
