OK.  We're aware of that problem and are working on it ;)

Right.  Unfortunately, if you make a hot update system's design too 
simple, it can be dangerous and will potentially do more harm than good.

If there's anything that I can do to help people understand our code and 
why we think that it's as simple as you'd want a hot update system to be, 
please let me know.
