* Remove unnecessary locking

* rustfmt

* Try fix MSRV issue

* Revert (original change red herring)

Technically this is not an MSRV issue, this is an actions + not commiting Cargo.lock issue, since having async_global_executor on 2021 should be fine as long as your compiler is also on 2021, and xtra won't specifically bring in the 2021 edition as it.
