From the other responses, it looks like the hole is 2.25GB, at least in Jaguar. So the 4GB of memory address space is most likely only going to be used by people working on multiple documents in one program, versus people working on one big document, which presumably need to be in contiguous memory, I would think.

Hopefully this contiguous hole limitation will be eliminated if Apple moves to a 64-bit address space.
