This fixes and issue with delays between synchronous calls to phantom using "run" function.
In old version when synchronous function was called heartbeat was sent as well cluttering phantom stdin.
Between "_send" and "_receive" actions node was sending heartbeat messages which had to be processed by the phantom - even though code run on phantom was synchronous.
