Right now you can specify opts.outputs as a function, and thus no need to plugin factor-bundle each time reset.

I have tried some way to use watchify with factor-bundle, no memory leak detected.

I think plugging factor-bundle repeatedly seems a little odd, because reset only rebuild the pipeline, and all other plugins are plugged only once.

@zoubin you are correct i tired it out by moving factor-bundle outside of my re-bundling method and it works therefore this fix is un-needed at least for me as well.

my simple setup using browserify-incremental + chokidar

var bundleStream = browserifyInc(files, {
    cache: {},
    packageCache: {},
    fullPaths: true,
    cacheFile: 'browserify-cache.json'
}).plugin('factor-bundle', {
    outputs: outputFiles
});

var bundleScripts = function bundleScripts() {
    bundleStream
        .bundle()
        .pipe(fs.createWriteStream('./client/dist/js/common.js'));
};

I think this may be my issue as well.

Alright, it sounds like this fix isn't really necessary, and @zoubin and @davidchase have solutions. I'll close this PR.
