I have finally come to the bottom of my inquiry into uClinux and busybox/init.

1. uClinux-dist maintains a patch against busybox, which (possibly
among other things) includes...

> #if defined(__UCLIBC__) && !defined(__UCLIBC_HAS_MMU__)
> #define fork	vfork
> #endif

2. uClinux-dist does not use busybox/init by default anyways, instead
using simpleinit, which is fork/exit vfork/_exit clean.
