After discussed with @dan-blanchard , I gave up introducing new multilang
heartbeat mechanism.
It would be new requirement to storm multilang libraries, which library
developers already struggled with current heartbeat mechanism.
Above all, I can't think about overcoming GIL.
I'll close this issue, but to stick with current mechanism STORM-742 should
be merged.

> Having design constraint of multilang heartbeat, some issues are raised at
> the moment.
> (https://issues.apache.org/jira/browse/STORM-738 is a kind of reporting)
> I'm trying to add workarounds
> (https://issues.apache.org/jira/browse/STORM-742 and so on), but if we can
> get rid of design constraint it would be really great.
> Maybe we can use pid file of subprocess (subprocess write it from sendpid())
> to check subprocess heartbeat from ShellSpout / ShellBolt.
> Letting subprocess launch new thread which writes pid file periodically, to
> make sure "modified time" of file is periodically up to date. (It is just an
> idea, and it should be validated.)
