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.

always return an 8-byte value (or void) from native functions called from Java
...
This is important on the 32-bit OS X PowerPC ABI, since the location
of the low 32-bits of a return value change depending on whether the
entire value is 64-bits or not.
