Fix recursive function

[guillaumepalayer]

When you have a few thousands files and you run the option task newFilesOnly, an error occurs Maximum call stack size exceeded. Fix this issue by scheduling the "immediate" execution of callback after I/O events callbacks and before setTimeoutand setInterval — More info on setImmediate function here: http://nodejs.org/api/timers.html#timers_setimmediate_callback_arg

@andismith Any chance of merging this in? I had the same issue as @guillaumepalayer and this fixed it for me too. (I've over 5,000 images.)

@guillaumepalayer This should work for Node 0.8, too.

(setImmediate || process.nextTick)(callback);

(Though I haven't tried it :smile: )

@benurb Thank you for the trick. I will try that soon.
