When using boot watch test I have a very frequent error:

clojure.lang.Compiler$CompilerException: java.lang.OutOfMemoryError: Metaspace, compiling:(ragtime/protocols.clj:3:1)

I have not counted the time it takes but my feeling is every 20 mins of the tests running. I already have a pretty high configuration, which I gathered from the boot wiki (but might be off):

export BOOT_JVM_OPTIONS="-Xmx2g -client -XX:MaxMetaspaceSize=1g -XX:+TieredCompilation -XX:TieredStopAtLevel=1 -XX:+UseConcMarkSweepGC -XX:+CMSClassUnloadingEnabled -Xverify:none -XX:-OmitStackTraceInFastThrow"

What else can I tweak? I also briefly investigated if it was pod/pod-pool's fault in a way. It probably is, but I could not figure out way during my first attempt.

Fix memory leak in pods

This was particularly evident when doing `boot watch test` and has been fixed thanks to Micha's
intuition of adding a clojure.core/shutdown-agents in boot.pod/destroy-pod.

Add boot.pod/*destroy-pod-hook*
d36ee42 
In order to fix memory leaks in task-local pods, we need a way to execute custom cleaning at pod
destroy time. This was particularly evident when doing `boot watch test` in a resource heavy app.
