1## Multiple runtimes
2
3Sometimes, a Wasm module might want a stateful host module. In that case, we have to create
4multiple `wazero.Runtime` if we want to run it multiple times.
5This example shows how to use multiple Runtimes while sharing
6the same compilation caches so that we could reduce the compilation time of Wasm modules.

8In this example, we create two `wazero.Runtime` which shares the underlying cache, and
9instantiate a Wasm module which requires the stateful "env" module on each runtime.
