Snapshot difference disk allocation size.

[rgesswein]

I notice a lot of disk activity when using snapshots. An initial "current version" difference disk of a snapshot takes, for me anyway, takes a few hundred MB and after a few days ends up taking 1 to 3 GB. I'd like to suggest a way to allocate these difference disks in much larger chunks. Say 100MB or more per allocation. This would certainly speed up initial runs of snapshot disks and would probably lower fragmentation quite a bit.
