So am I correct in saying that the text is modified on initial load and,
as long as the revisions of the libraries are the same for each new
instantiation, the text is still sharable between process?
Note that this also implies that the binary image on disk is insuffient
to use for recovering pages that have been removed from the processes'
working set. These processes will need to have space allocated in the swap
space on disk and treated similarly to data pages (at least when initially
removed from memory, then it never changes again so it will not need to
be written out again).
