    Right now the only way to specify the spark-shell memory is to use the 
now-undocumented SPARK_MEM environment variable. I have raised this issue on 
the JIRA ticket that deprecated SPARK_MEM 
(https://spark-project.atlassian.net/browse/SPARK-929), and the resolution 
there may affect how we want to proceed here.
    
    (As an intermediate solution, you can always just add an option which sets 
SPARK_MEM, and we can change that later to something like SPARK_DRIVER_MEM when 
we add it.)
