    @dashengju 
    I filed new issue regarding very busy bolt with Non-ACK mode. https://issues.apache.org/jira/browse/STORM-758
    Maybe you would be interested that instead of this, so please have a look at my idea in new issue.
    Thanks!

> As [~dashengju] stated from STORM-738, very busy ShellBolt subprocess cannot respond heartbeat just in time.
> Actually it's by design constraint (more details are on STORM-513 or STORM-738), but ShellSpout avoids constraint by updating heartbeat at any type of response from subprocess.
> We can apply this approach to ShellBolt and let ShellBolt avoid design constraint, too.
