If you need an asynchronous-friendly version of Array.forEachArray.forEach and similar, they're available in the Node.js 'async' module: http://github.com/caolan/async ...as a bonus this module also works in the browser.

async.each(openFiles, saveFile, function(err){
    // if any of the saves produced an error, err would equal that error
});

A code example here is helpful because it tells people which function to use within async to do the forEach
