Most pagefile accesses are random and read or write very small blocks
(16KB on Darwin AFAIK). File fragmentation hurts mainly when accesses
to the file are long and sequential. If accesses are short and random,
it makes little to no difference if the file is fragmented, especially
the smaller the access is.
Do not post admin requests to the list. They will be ignored.
