It's a feature, the virtual machines take care to only open the image
file as read-only and read it into memory, then close it.
Optionally on the macintosh, and always on the iPhone the image could
be mmapped by the Virtual memory manager's file vnode mapper instead
of being read into memory in a single read.
It's only opened as writeable if you save the image.
The changes and source file if found are opened and managed like so:
/Users/johnmci/Documents/Squeak3.8.0/build/SqueakV39.sources
{If found, this is opened read only}
/Users/johnmci/Shared/PharoCore-1.0-10451-BETA/PharoCore-1.0-10451-
BETA.changes
{If found, this is opened first as read/write, but can fall back to
read only}
The error generated by not finding the changes/sources depends on your
image preferences. IE ignore missing changes/source file
