I think go-ipfs has the concept of command requirements, perhaps we need something similar i.e. jsipfs cid does not require a repo so shouldn't need to obtain a lock.

@alanshaw unfortunately still getting this issue, with this node program:

const IPFS = require('ipfs');

const init = () => {
  const ipfs = new IPFS();

  ipfs.on('ready',  () => console.log('ready'));
  ipfs.on('error', err => console.log(err));
};

init();

The error is being caught in the error event listener:

{ Error: Lock file is already being hold
    at options.fs.stat (<repo-path>/node_modules/proper-lockfile/lib/lockfile.js:54:47)
    at <repo-path>/node_modules/graceful-fs/polyfills.js:285:20
    at FSReqCallback.oncomplete (fs.js:160:5) code: 'ELOCKED', file: '/Users/<me>/.jsipfs' }

node: v11.9.0
ipfs: ^0.34.4

Running this program several times in a row (one after another, not simultaneously) will cause the error to happen. If I stop, wait a bit, and run it again, it sometimes works. Seems like it could be related to #229. How can i help?
