This doesn't work since dofile() is a library function written in
C and you cannot yield across a C call boundary (search the
archives for lots of explanations about this).

But you can just replace
  dofile(name)
with:
  assert(loadfile(name))()

That's a plain call in the 2nd case, so you can yield from inside
the second file.

You should really check the result of coroutine.resume(), e.g.:
  assert(coroutine.resume(cof))
Then you would have noticed the error:
  "attempt to yield across metamethod/C-call boundary"
