Sorry, something went wrong.
Store the full information we have on a given `SharedArrayBuffer`, and use the deleter provided by the JS engine to free the memory when that is needed. This fixes memory lifetime management for WASM buffers that are passed through a `MessageChannel` (e.g. between threads).

Fwiw, I’ve extended the test a bit. (@devsnek I’ve also figured out that we can’t transfer WebAssembly.Modules yet the way we should – also working on that.) New CI: https://ci.nodejs.org/job/node-test-pull-request/19915/ |
