Thanks, I wouldn't have thought of doing the accept call in handle_info.

Is there any advantage of spawning a new acceptor process every time a
new connection arrives and do the request processing in the original
process, as opposed to spawning a new worker process on each request and
using a single acceptor?

Thanks again,
