Clarifies a userland invariant until a better
solution can be found.

Also moves a misplaced sentence from _write to
write.

I think this depends on #31317.

I think this depends on #31317.

How so? This is a timing issue related to when and how the _write callback is invoked by the user.

The callback method will always be called asynchronously

Perhaps I'm misunderstanding this? Note "always". Or does that mean that if the callback is called it will be called asynchronously?

Ah now I see what you mean. That part was incorrectly written at _write() instead of write(). I just moved it to where it was intended. That was not the primary purpose of this PR.

And yes the "always" is a bit ambigious but I think the intention is that "is called it will be called asynchronously". Maybe removing "always" would amke it clearer?

This does not land cleanly on v13.x. Could you please open a backport PR if it should land on that branch

I think 75b30c6 must be backported first. Then this will land cleanly.

75b30c6 is semver-major, so this should not be backported.
