Save the setImmediate() callback arguments into an array instead of a closure, and invoke the callback on the arguments from an optimizable function. 60% faster setImmediate with 0 args (15% if self-recursive) 4x faster setImmediate with 1-3 args, 2x with > 3 seems to be faster with less memory pressure when memory is tight Changes: - use L.create() to build faster lists - use runCallback() from within tryOnImmediate() - save the arguments and do not build closures for the callbacks PR-URL: https://github.com/nodejs/node/pull/6436 Reviewed-By: Benjamin Gruenbaum <benjamingr@gmail.com> Reviewed-By: Jeremiah Senkpiel <fishrock123@rocketmail.com>
