*  batches. As such, we want to allow all modules from the same load.php
*  response to be written to disk with a single flush, not many.
*
* - Repeatedly deleting and creating timers is non-trivial.
*
* - localStorage is shared by all pages from the same origin, if multiple
*  pages are loaded with different module sets, the possibility exists that
*  modules saved by one page will be clobbered by another. The impact of
*  this is minor, it merely causes a less efficient cache use, and the
