Restart the application. Run it. The combined cached my_key.js file
still only includes "a" and "b", the cached file was not invalidated
when I added "c" to it. I had to go and find the file and rm it myself.

missing? Under what circumstances is the cached file supposed to be
regenerated? If the last-modified timestamp changes on one of the
included files, will it be regenerated? Will it EVER be re-generated?
