doc: why saying "Create" while the API returns a reference of existing one

[keepsimple1]

mio/src/poll.rs

Lines 332 to 336 in edc0c76

	/// Create a separate `Registry` which can be used to register
	/// `event::Source`s.
	pub fn registry(&self) -> &Registry {
	&self.registry
	}

I'm confused about the doc comment of "Create a separate Registry" while the function returns the reference of existing registry. Did I misunderstand it?

We can change it to Returns a Registry
