Calling finishShutdown() immediatelly after startShutdown(), without waiting for the plugin to call proxy_done is technically incorrect, and effectlively a no-op. This sequence works only if the plugin returns true from the proxy_on_done callback, in which case you don't even need to call finishShutdown().

It also breaks the promise of not executing anything in the canary (e.g. you can imagine plugins sending batch reports on shutdown, etc.), which is why we're simply dropping the VM right now.

}

std::shared_ptr<WasmBase> &wasm() { return wasm_base_; }
