alexcrichton opened PR #11686 from alexcrichton:wasmtime-wast-new-store-per-component to bytecodealliance:main:

This commit refactors the wasmtime-wast crate to place each component in its own store. This is in contrast to core wasm testing where all instances get placed in the same store. The reason for this is that components, in particular async state, is only fully defined so long as a trap doesn't happen and once a trap happens it's expected the entire store is torn down. This removes the need for the store to keep track of exactly which instance all async tasks are associated with to ensure that once any of them trap only the precise set of tasks necessary are torn down. Instead Wasmtime can rely on embedders throwing away Store<T> entirely.

The refactoring here provides a hook in WastContext to configure the store but otherwise a new store is manufactured for all component instances. Core wasm is unaffected. Tests are also unaffected as same-store behavior isn't actually required by any tests.
