connection_fix.rb

from gist.github.com/238999

If your workers are inactive for a long period of time, they’ll lose their MySQL connection.

This hack ensures we re-connect whenever a connection is lost. Because, really. why not?

Stick this in RAILS_ROOT/config/initializers/connection_fix.rb (or somewhere similar)
