Ok... I know what was missing above.  I missed the part about the parent
continuing execution when the child does an execve.  

However, vfork on i386 is definitely broken.  A test program to illustrate this
is attached.  The child executes but the parent segfaults.

As a temporary work-around, I'm making vfork on i386 a weak alias for fork.
