Yes, for arrays larger than 2kB, the allocation length information is 
placed before the actual data, and ret.ptr has an offset of 16 bytes 
into the allocation block. As a consequence, applying 
BlkAttr.NO_INTERIOR will very likely cause the block to be collected. 
NO_INTERIOR has no effect for smaller blocks.

That's why the existing AA code explicitely uses GC.malloc instead of new[].
