Or can be configured to not use fork().  Yes, I'm aware of this.  However, 
when using vfork() it has to exec something to unblock the parent.  (See svn 
15380 for a start of support for that, making /proc/self/exe a config 
option.)  Having a config option to just fork() and not exec anything may 
actually be worth doing for standalone shell mode, I haven't decided yet.
