NAME
set_heart_beat() - enable or disable an object's heartbeat
SYNOPSIS
int set_heart_beat(int flag);
DESCRIPTION
Enable (flag == 1) or disable heart beat (flag == 0). If the heart beat
is not needed for the moment, then do disable it. This will reduce system
overhead.
Return true for success, and false for failure. Specifically, it will
fail if the heart beat function has been disabled, which it will be
if there is a run time error in the object.
