If you're forking, the easiest option is not to exec() -- make your child
code part of the same executable.  If you mmap a region with MAP_SHARED
(maybe you will no longer need MAP_FIXED?) and then fork() *without* exec(),
the mapping will be shared among the children automatically, and at the same
virtual address.
