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)...
