Instead of block zeroing hashtableEntry, you could add a field to zero in
between _hash and _next and that would not have stray unaligned bytes.
template <MEMFLAGS F> class BasicHashtableEntry {
friend class VMStructs;
private:
unsigned int _hash; // 32-bit hash for item
// Link to next element in the linked list for this bucket.
BasicHashtableEntry<F>* _next;
