I feel emphasizing that its a cell that manages a single in flight Task is better served by this name, i.e.:

• yes it caches, but handles expiration too
• half the point is that it doesn't cache failures
• it is mainly Task based (though it supports Async)

But...

• it uses an AsyncLazy internally, and is arguably an extension to that, which might suggest AsyncLazyCell as a better name
• maybe AsyncLazy should also be renamed to LazyTask given how it deviates from the original AsyncLazy?
