Reconnect on unicorn USR2 about readthis

[sorentwo]

@justindowning: You don't need to force redis to reconnect, it will automatically reconnect when it encounters inheritance errors. There is a test for this exact use case in the redis-rb repository: fork_safety_test.rb

readthis uses connection_pool to manage multiple connections. While it would be technically possible to iterate over each connection in the pool and force a reconnect, it isn't necessary. In fact, the connection pool documentation even mandates that connections be self repairing!

There is no provision for repairing or checking the health of a connection; connections should be self-repairing. This is true of the Dalli and Redis clients.

So, good news all around. You don't need to do anything!
