SPARK-1572 Don't kill Executor if PythonRDD fails while computing parent
Previously, the behavior was that if the parent RDD threw any exception
other than IOException or FileNotFoundException (which is quite possible for
Hadoop input sources), the entire Executor would crash, because the default
thread a uncaught exception handler calls System.exit().
This patch avoids two related issues:
1. Always catch exceptions in this reader thread.
2. Don't mask readerException when Python throws an EOFError
after worker.shutdownOutput() is called.
