Which is why they usually don't do what was proposed, but something similar:
they keep information saved to disk, usually only unsaved changes to open
files. Changed settings, undo history and other program state is usually not
saved. Even if more information is saved, it's in a serialised format, not an
image dump.

Imagine the user upgraded the application while it was running. A restart
would mean loading a memory dump from a "foreign" application and would
introduce further problems.
