Return the memory block at the specified `address` back to this allocator. If `address` is 0, this function has no effect. The behavior is undefined unless `address` was allocated using this allocator object and has not already been deallocated. Note that `std::free` is _not_ called when `address` is 0 (in order to avoid having to acquire a lock, and potential contention in multi‐treaded programs).
