Node inspector doesn't work: address already in use

[shumkov]

Hello guys, thank you for your amazing work.

I use ipfsd-ctl for spawning IPFS instance in mocha test in a very similar way as in OrbitDb tests.
It's cool but it doesn't work with node inspector:

node_modules/.bin/mocha --inspect test/**/*.js

Unfortunately, thats a known (and annoying ) issue. debugging doesn't work with forked processes in nodejs - nodejs/node#9435

[shumkov]

Ahh... Do you know any workarounds? Like this one askmike/gekko#1666?

[dryajov]

@shumkov Interesting, thanks for pointing that one out - it's worth a try for sure. Would you feel comfortable sending a PR that fixes this?

[vmx]

I just ran into this issue and didn't know there was already one open. I'll do a PR soon.

@dryajov @vmx Seems I'm late :) Don't hesitate to ask my help if needed.
