877301 - [meta] network cache rewrite

Status: RESOLVED FIXED

(Core :: Networking: Cache, defect)

Description

[Jason Duell]

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).
