Module async_refcell 

AsyncRefCell<T> — an async-aware RefCell.

borrow() / borrow_mut() return futures that wait until the cell is available instead of panicking. Built on top of AsyncCondition: when the last outstanding guard is dropped, all waiting borrowers are woken and race to re-probe the underlying RefCell. Losers re-queue.

This is a single-threaded primitive — it holds a RefCell internally and is !Sync. For cross-thread sharing, use a proper mutex crate.
