Title: Making async.forever run... forever =)

Previously, if async.forever was called, since it wasn't using `setImmediate` --
the max call stack size would be exceeded rather quickly.

This fix introduces setImmediate behavior to prevent user-generated tasks from
starving the event loop of resources.

Fixes #437.
