True, but the actual 'lock' counter is stored in the chunk, which is
accessed via the pointer. So MemPtrUnlock is VERY slightly faster, because
it does not need to dereference the handle.
Note that this will NEVER be a performance bottleneck for your code, so you
shouldn't care. If you happen to have both the handle and the pointer
lying around in registers, use the pointer. Otherwise, use whichever is
most convenient.
If you find yourself optimizing at this level, you need to remember that
you can't optimize too soon. :-)
