Computer education time:

A vpus is a virtual machine and it uses a percentage of the hardware. For example, the CPU can handle up to 32 "cores" so i could run 32 clews on it. But, each instance would take up 1/32nd of the hardware. If i let clew live on the whole thing, it would basically never get bogged down by hardware.

At least for awhile. My internet speed would give out before the hardware gets overworked.
