> I've created a patch that demonstrates this. In the patch, code is added to
> UnsafeDirectLittleEndian to track all the instances of that class that are
> created (which happens when buffers are allocated inside TopLevelAllocator).
> release() is overridden to remove these from the tracked list when they are
> released. An @After action is added to TestTpchDistributed which checks on
> the count of outstanding buffers. If the test is run, every case fails, and
> each failure shows a progressively larger and larger number of outstanding
> buffers. There are no complaints from the allocator.
