It cannot be done portably, but with certain restrictions, it can
almost always be done.

Franz does it unportably: it writes its text image, then its data.  It
puts an appropriate executable header on the front, and adds a symbol
table.  When it starts up it checks to see if it was doing something
special before.

Note that file descriptors are generally lost, and that saving the
environment is sometimes wrong.  Generally, the best way to save state
is to save the important stuff instead of blindly writing everything.
