sass followup: how much memory would you expect it to require? "It works on my machine" (ie when run locally), but when I run it remotely, lein sass fails with java.lang.OutOfMemoryError: Java heap space

project.clj contains :jvm-opts ["-Xmx2g"] and circleci config contains JVM_OPTS: -Xmx3200m

...needed to set LEIN_JVM_OPTS it turns out. Now it works 👌
