Fork may be impossible, but how about vfork?  You wouldn't have to do 
any relocation, just establish a separate thread of execution.  And some
way to tell from exec which thread you were running, so you know whether
to start up a new process or not.

Yeah, I know it's gross, but it would handle 90% or so of forks people do.
