- fragmented transfers. Lower target levels should not implement
- hacks, such as enlarging the transfer, in an attempt to compensate

- With that available, the lowest target can safely and freely "push"

- NOTE: cagney/2003-10-17: Unlike the old query and the memory

- NOTE: cagney/2003-10-17: Just like the old query and memory xfer
- methods, these new methods perform partial transfers. The only
- difference is that these new methods thought to include "partial"

- confusion and duplication of effort as each target object attempted
- to locally take responsibility for something it didn't have to
- worry about.
