- Coherent cache memory is used in libbsd for things like descriptors
and it optionally clears the memory on allocation. Test is works.
There is no guarantee that memset() and memcpy() work with cache coherent
memory. Such memory areas may disallow misaligned access for example.
That seems reasonable however this change about testing the implicit
requirements we have that memset works. LibBSD requires memset works ...

Using memset() here could be a bug in libbsd.
