> The error below happens. This happens because the test starts and stops a lot
> of bookies, and hedwig hub for each test. Each of these allocates some Direct
> Buffer memory, which doesn't automatically get returned the the pool once the
> test is finished. The DirectByteBuffers do seem to be garbage collected, but
> they don't actually clean up the direct buffer memory until an internal
> cleaner runs later. I can't find a way to run this manually.
> This happens since BOOKKEEPER-65, as the new netty allocates more direct
> buffers. A work around for the problem for the moment is to run test with 1G
> heap.
> $ mvn test -DargLine="-Xmx1G"
