While it's true LIVY-424 creates a session leak due to REPL leak in Scala it's not the only
thing that can.  I've run hundreds of simple scala commands and the leak is only mild/moderate.
  However, some scala commands can be really problematic.  For instance

import org.apache.spark.sql._

run this import repeatedly and within only 10s of executions your sessions performance will
degrade and eventually run out of memory.
