Added caching to the two_random_images method, meaning images should only change once every minute.
Seeing if Entry.all actually reduces the memory required to run the app.
Attempting the find_in_batches fix for the memory usage problem.
Possibly vain attempt to reduce the amount of objects in memory.
Wrote my own mini-serialization to avoid instantiating all the objects at once. Testing on heroku now.
Removed p
Attempting to work around the memory issue using a rake task
Attempted to sort out Memcache memory limit
Round 2, fight
Still hunting for a solution to this.
Memcachier employee solution. Really need to just port to NOREL db...
Config funsies
Yet another attempt
yay
Reduced size of object hashes in an attempt to reduce the size of the whole dataset.
Implementing Redis as a cache, to see if it is more effective than memcache for my needs.

Changed the two caching methods to reflect the $redis syntax

Added an initialiser for Redis to create a global variable. This ought to work for prod but isn't set up for dev.

Switched off initialisation at precompile, as a known Heroku error
Turned off :redis_store as the specific cache_store.
Moved the initialise on precompile, in the hope that this positioning actually works
Trying to find a home for this sad little line of code.
trying without it
