No. Threads are the underlying thing that coroutines are implemented
on top of. Coroutines are threads created in a particular way with a
specific target function, that can be resumed and yielded, but not all
threads are set up this way - if you create a thread via the C api
that has nothing on its stack, that is not (yet) a coroutine.
