+Install thread excepthook.
+By default, all exceptions raised in thread run() method are caught internally
+by the threading module (see _bootstrap_inner method). Current implementation
+simply dumps the traceback to stderr and did not exit the process.
+This change explicitly catches exceptions and invokes sys.excepthook handler.
