Why not test with a RPC/server that throws an actual exception ?

Problem
With
autothrowenabled,ReceiveMessage()can throw out ofMessageWaiter.HandleCallback()instead of rejecting the promise that owns the async read.Change
Catch the receive exception, clear the async waiter registration and reject its deferred promise. Return completion so the callback helper releases the registration normally.
Validation
system.nodejs.test_async_ipc: fails before, passes after. Covers both async request/receive APIs, an unrelated promise and a subsequent successful request.No protocol or public API change. Validated on the official 6.2 image for GitHub main
a91a7a28, with the candidate sources installed. Full upstream CI has not been run.
