---------------------------------------
This seems like good idea. Stick up a patch.

> -XX:MaxDirectMemorySize is an artificial governor on how much off heap memory can be allocated.
> It would be nice to specify explicitly because:
> # The default can vary by platform / jvm impl - some devs may see random fails
> # It's just a limiter, it won't pre allocate or anything
> # A test env should normally ensure a healthy limit as would be done in production
