The PR uses a technique similar to #885 to speed up the recursive copy operation.

As fs-extra is built on top of graceful-fs, this change won't cause EMFILE: too many open files as graceful-fs will exponentially backoff and retry.

Change looks good to me; but would like a second pair of eyes here to make sure I'm not missing something.

@RyanZim ❤️

Too bad I can't port this change to Node.js' fs#cp. Node.js doesn't have graceful-fs, thus EMFILEcan not be avoided.

You'd have to implement a concurrency limit yourself, I guess.
