+Subject: [PATCH] Cleanup Region Files Direct Memory on close
+
+Mojang was semi leaking native memory here by relying on finalizers
+to clean up the direct memory.
+
+Finalizers have no guarantee on when they will be ran, and since this is
+old generation memory, it might be a while before its called.
