Hi Tristan,

how about the async-refresh package

Looks close to what you have written — from the README:


This is Haskell library implementing the logic for refreshing of
expiring data according to user-provided actions.


* Create a new configuration using newAsyncRefreshConf, providing the
  action to be used for data refreshing.

* Adjust the configuration using the asyncRefreshConfSet* functions,
  in particular using asyncRefreshConfSetCallback.

* Use newAsyncRefresh to initiate a new thread managing the
  asynchronous refreshing.


It is currently used by the package async-refresh-tokens
(https://hackage.haskell.org/package/async-refresh-tokens), which
specializes the async-refresh package to the refreshing of expiring
authentication tokens.

If you have questions or suggestions, feel free to open issues and/or
contact me directly.
