Hi Phil,

One thing you might find interesting - a small, crude experiment suggests that changing maxBlocking.erl to use process hibernation for those dormant processes could almost double the max number of processes Erlang can support.

I changed maxBlocking.erl's final few lines to read

    p() ->
        erlang:hibernate(?MODULE, q, []).
    q() ->
        receive
            "hello" ->
                io:format("Hello")
        end.

RabbitMQ uses hibernation in many places to reduce memory usage when many resources are being managed by the server.
