Thanks. I've noticed this patch would cause some tests failed. I will try to fix that. |

Change itself LGTM but the commit log needs to confirm to the guidelines from CONTRIBUTING.md. |
The debug process running "node debug a.js" will be stuck when the script ends. This is because the debug handler has been unrefed. We shouldn't unref the debug handler to avoid this problem.

For a simple javascript file:
Run
node debug a.jsto launch debug process. Press firstcand the program outputs> debug. After that, presscagain the process just gets stuck and has no response so we have to kill it.This is because debug handle has been unrefed. Once the program is finished, the event loop will be exited and the debug process will be stuck when debug sends commend again. We shouldn't unref the debug handle because even the script is finished, we can still send more debug command such as
restart.Fixes #1788.
