Reloading own lib in QGIS python console?

Question

I´m working on a main script with additional code based in a lib folder like this:

main.py
\mylib
  util.py (contains the class Utility)
  node.py
in main.py I´ve imported mylib like this:

from mylib.util import Utility
x = Utility()

It seems like QGIS python console caches the mylib on startup - changes made to the Utility class made after startup is ignored.

Is there a way to reload mylib without restarting QGIS?
