01bfa5ebf3 Flock: Creating the hypervisor and the external-contact process 
This is the first part of rewriting Flock to C to significantly reduce
memory footprint of individual machines from 20+M in Python to (goal)
less than 1M. Now the process eats ~460k and I suspect that this won't
even be the consumption per machine in total as fork() is involved and
some parts of the memory will be heavily shared.

constrained environments where every 100k of RAM matters.
