module SlavePools::QueryCache
duck-types with ActiveRecord::ConnectionAdapters::QueryCache but relies on ActiveRecord::Base.query_cache for state so we don't fragment the cache across multiple connections
we could use more of ActiveRecord's QueryCache
if it only used accessors for its internal ivars.

select_all
is trickier. it needs to use the master connection for cache logic, but ultimately pass its query through to whatever connection is current.
