  Is it really important that they be reloaded automatically as soon as they change?  What if several modules are being updated in concert, and the change is noticed before all of the files have been updated?  Won't the source be in an inconsistent state and probably take down, or at least effect negatively, the server?

  I would put a big fat (possibly figurative) button on the application somewhere and press it when I wanted the source updated.
