Now that we have the address arbiter extracted to its own class, we can fix an innaccuracy with the kernel. Said inaccuracy being that there isn't only one address arbiter. Each process instance contains its own AddressArbiter instance in the actual kernel. This fixes that and gets rid of another long-standing issue that could arise when attempting to create more than one process.
