Restart seems to be incompatible with --debug node option and npm run

[jcollum]

Building a Hapi.js API. I'd like supervisor to restart the process with --debug via my package.json:

"debug": "./node_modules/.bin/gulp transpile &&  node --max-old-space-size=8192  --inspect --debug=5567 dist/index.js  | ./node_modules/.bin/bunyan -o short",
 "watch": "./node_modules/.bin/supervisor --RV -s -e coffee,yaml  --watch src,config -x npm  -- run debug"

Ideally I'd run npm run watch and it would run the npm run debug script. Works fine -- once. After it restarts all it will do is attempt to start then hit an error and restart (loop):

Unable to open devtools socket: address already in use

If I take off the --inspect call I get this error:

Error: listen EADDRINUSE :::5567

Even with no --debug flag at all I still get an error on restart but this time it's in the Hapi API:

  "code": "EADDRINUSE",
  "errno": "EADDRINUSE",
  "syscall": "listen",
  "address": "0.0.0.0",
  "port": 5566

Adding in -k to the supervisor call doesn't work. I don't have anything listening to SIGTERM.

I'm trying to keep all my runs scripts in package.json, so adding a new gulp task is something I'd like to avoid.
