> DrillRuleSets.java lazily creates a list of rules that are used to decide on optimizations.
This is done lazily because some of the rules require some context to operate on. However,
the ones that do capture context that should not be used after the current query completes.
In particular, the new allocator has caught later queries using the allocator created (and
since closed) for the first query executed on the drillbit.
