benchmark:
- system
hardware: 2 x 2.5GHz P4, 1GB RAM, 15k SCSI, ReiserFS

no mmap windows mmap windows
cpu-bound real 0m3.712s real 0m3.970s

not quite sure why sharpen is a little slower (4%?) ... IO speed is about
the same though ... worst-case is having to constantly move windows about
(500,000 page faults, vs 10,000 for no windows)
again, with an image larger than RAM
no mmap windows mmap windows
io-bound real 2m52.759s real 2m11.172s

user 0m19.850s user 0m26.600s

mmap windows actually slightly faster in this case ... plus they stress the
OS less
