Using ipc::Shmem causes unbounded shmem use growth until e.g. a Worker yields to the event loop. If a Worker never yields, Shmems sent to WebGLParent are never released. Specifically the manager (PCanvasManager) for WebGLParent calls DestroySharedMemory, which sends/enqueues for WebGLChild's manager a matching call to ShmemDestroyed. However, while WebGLChild refuses to spin its event loop (such as a no-return WASM Worker), the ShmemDestroyed events will just pile up. Closing e.g. the tab frees the shmems, but they accumulate unbounded until the Worker yields to the event loop. This is true for other users of ipc::Shmem (or RaiiShmem) as well, but entrypoints other than DispatchCommands are rarer and can be handled later similarly.
