      Description

      The runCommand code in Shell.java can get into a situation where it will ignore InterruptedExceptions and refuse to shutdown due to being in I/O waiting for the return value of the subprocess that was spawned. We need to allow for the subprocess to be interrupted and killed when the shell process gets killed. Currently the JVM will shutdown and all of the subprocesses will be orphaned and not killed.
