If i am writing a multiplatform lib targeting android, ios and js, what is a good solution for multiplatform caching for example the LoadingCache pattern

Lets say i have a 

```suspend fun refreshToken(token: Token)```
if the cache is cold, I want to prevent coroutines concurrently refreshing the value

I have tried some solutions 

Semaphore (the coroutine aware one)
Actor-like impl with channels but without actor lib. 

Are there any other simpler/more obvious solutions?
