start implementing new proc/rpc handling

+ Essentially, separate root process and remote procedure call handling.
  I really should write down some documentation so I don't forget, but
  essentially: All threads share a common process virtual memory, and
  when a thread wants to make an rpc, it switches over to its own rpc
  vmem space that is linked to the remote process.
