Apache Drill lists dead/killed queries as 'Running Queries' in the UI

The Apache Drill UI lists queries that are dead/have been killed as 'Running Queries' on the 'Profiles' page.

When grepping for the Query GUID of a dead query that is listed as currently running in the drill directory, I found the following outputs in a drillbit.log:

There needs to be some logic which moves these queries from the 'Running Queries' section to 'Failed Queries' or something to that effect.
