I fixed a caching problem for modutils. Also, since I'm defining the
cache_invalid function, I thought it would be more efficient to define a
_modutils function, and call that at the end of the script (to avoid
redefining the cache function every time).

I also changed sw from 2 to 4 (cosmetic), since the other files seemed
to have 4.
