that's entirely by accident...

PIL uses memory mapping on certain uncompressed formats
(where the layout on disk happens to match any image memory
layout supported by PIL).  Mapped formats include TIFF, BMP,
PPM, and IM.

PIL 1.1 is basically a maintenance release.  Here's an excerpt
from the CHANGES file:

*** Changes from release 1.0 to 1.1 ***

+ Adapted to Python 1.6 ("append" and other method changes)

+ Fixed Image.paste when pasting with solid colour and matte
  layers ("L" or "RGBA" masks) (bug reported by Robert Kern)

+ To make it easier to distribute prebuilt versions of PIL,
  the tkinit binding stuff has been moved to a separate
  extension module, named "_imagingtk".
