* Major:
- Moved sandbox data struct into linear memory of a sandbox.
- (Should work well with other sandboxing mechanisms).
- Removed all mallocs from within uv usage, using a pre-allocated
memory within sandbox data-struct for read/write.
- TODO: convert prints on stdout to a string and send it out with
function response body.
- TODO: for each function loaded, what is the request and response
http header/body specification.
To start, keep headers minimal.
body either: json, plain.
- TODO: track TIMEOUTS. If we go beyond that, return a HTTP 408?
