> When StramLocalCluster is run asynchronously it may be shutdown during StramLocalCluster
initialization leading to termination without performing necessary termination sequence. Runtime
exception during the run may also lead to improper termination sequence. For example:

> Exception in thread "master" java.lang.RuntimeException: java.lang.InterruptedException
> 	at com.datatorrent.bufferserver.server.Server.run(Server.java:154)
