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.

Debug: Do not compile allocator debug journals in unless requested.

These journals can become very memory-heavy when it comes to
constrained environments where every 100k of RAM matters.
