OK.  That's good for consistency if anything else.

We have a test framework for doing unit test at such low level, yet
we cannot really write tests that validates that the right thing
happens when a particular realloc() call returns NULL, which feels
somewhat disappointing, but that is not a fault of this series.

Thanks.
