zero heap space ahead of time when allocating raw storage and garbage collecting, not when allocating individual objects
...
This helps us support the Java Memory Model without adding a memory
barrier to every object allocation. It's also potentially more
efficient, since we zero out each heap segment all at once instead of
bit-by-bit with each object allocation.

fix subtle bug in hashMapInsert which caused us to update the old array previously associated with the hash map, whereas a GC causes the table to be resized when a weak reference is removed and thus a new array used
