Freezes when updating multiple async atoms

[Thisen]

As a part of looking into improvements for useAtomCallback, I've stumbled upon a issue, see the CodeSandbox reproduction.

It looks like there's a freeze, when I click one of those listitems, and Jotai starts to update a bunch of async read atoms.

I've added some tests on a branch, where the tests passes, but you get warnings about [Bug] deleting atomState with read promise.

I'm looking into this help with the help of @dai-shi, so I created this issue for tracking/transparency.
