Something like this?

    It may be useful to take a checkpoint at 'main', and return
    to that checkpoint instead of restarting the program.  This
    will help keep things deterministic by avoiding random things
    that may occur during creation of a new process (such as
    address space randomization).

I don't really know about "address space randomization" (though
I can guess what it means)...
