    Description

      1. Define all the areas that use caching or should use caching (see subtasks of this bug)

      Existing cache systems:
      Access (Capabilities/Contexts)
      Files
      Themes/Images/JS caching
      Strings
      Database meta information
      Config variables
      User prefs
      Repository lists
      Cache flags
      Text cache
      Session
      RSS feeds
      Timezones

      Static caches:

      No caches yet:

      Please add comments here for any other hotspots you think of.

      TEMPLATE FOR EACH HOTSPOT:

      type of data
      data structure
      when it gets stored
      where it gets stored
      how it gets read
      does it need locking
      how it gets cleared
      typical sizes
      safeguards in place (eg limits)

      2. Fix all the subtasks.
