You can do this with `random', it seems from the docs.  Look at
`initstate' and `setstate'.  Note that a glance at the source doesn't
convince me that this actually works.

Otherwise, you could take `rand' from DJGPP's source (unless you plan to
sell this commercially without source); it should be obvious how to save
and restore its state (the state is a single variable).
