Daniel, could you please describe in some detail what happens now on
Posix systems when to_create_inferior is called, and in particular as
result of the call to `proceed'? AFAIK, the inferior is not actually
running until you say "run", but your message seems to indicate
otherwise?
I need these details to decide whether your suggested change in
go32-nat.c is the right thing to do. There's the prog_has_started
flag there that go32_create_inferior is setting after the call to
proceed. You suggest to remove the call to proceed, but the flag is
still being set, and I need to make up my mind whether this could
spell some trouble. If it does, we might need a new target op to
handle that.
I tried to understand what exactly does proceed do when called from
to_create_inferior, but got lost in twisty little passages, all alike.
I need help.

"create" or "create-inferior" sounds like a good name.
We would need a docs patch if we add a new command, of course.
