MaxListenersExceededWarning encountered

[jaydenseric]

When fs-capacity is used frequently in the same process, it can trigger MaxListenersExceededWarning (best debugged with the --trace-warnings Node.js flag):

(node:72923) MaxListenersExceededWarning: Possible EventEmitter memory leak detected. 11 exit listeners added. Use emitter.setMaxListeners() to increase limit
    at _addListener (events.js:243:17)
    at process.addListener (events.js:259:10)
    at _fs.default.open (/Users/jaydenseric/Sites/apollo-upload-server/node_modules/fs-capacitor/lib/index.js:140:17)
    at FSReqWrap.oncomplete (fs.js:145:20)

This should now be fixed on master and in v1.0.0-beta.*: https://travis-ci.org/jaydenseric/apollo-upload-server/jobs/406965783#L2203

I'm going to leave this issue open until I publish v1.0.0.
