This is a meta bug for the necko cache rewrite. Main goals are to
1) eliminate main-thread jank (from waiting for global lock while cache thread does I/O), which on some systems is >1 second at times.
2) Better crash recovery (don't throw out entire cache at unclean shutdown, and instead detect corrupt entries on a per-entry basis).
