     -- was this an optimization, with code working pretty much as before,
        but gaining speed from not doing a bunch of unneeded Copy-on-Write
        setup?

it was clearly an optimisation.  i'm sure this or some other
list has benchmark results for this, back from then.
   
     -- are there programs in-tree which depend on the shared address space
        semantics?

one hopes not :-)  infact, /bin/sh does not use it currently
because of this.  see the several attempts to fix it that have
been backed out :-)
   
     -- are there common third-party apps which do?

i don't know, but again, i hope not.
   
     -- what do other systems do?

don't know.
