Concurrency issues

[sheerun]

This plugin introduces concurrency issues in bower.

I received error when running following script with this bower.json:

{
    "name": "myApp",
    "version": "0.1.0",
    "dependencies": {
        "angular": "latest",
        "angular-bootstrap": "0.10.0",
        "angular-cookies": "latest",
        "angular-ui-router": "#master",
        "auth0.js": "https://github.com/auth0/auth0.js.git#v2.0.10",
        "auth0-angular": "latest",
        "bootstrap": "3.0.3"
    }
}

for i in {1..10}; do (mkdir $i && cp bower.json $i/bower.json && cd $i && bower install) & done

Additionally it removed all configuration so upon next execution of bower I got:

May bower anonymously report usage statistics to improve the tool over time?

This is an issue with configstore. config should always be an object, so clearly something wrong there. Can you make sure it's the latest configstore? And then open it over there instead.
