Not following.  Are you saying that the main executable gets mapped into
the process address space immediately, but shared libraries are not?

I wonder whether we could work around that by just destroying the created
process and trying again if we get a collision.  It'd be a tad
inefficient, but hopefully collisions wouldn't happen often enough to be a
big problem.
