sendAsyncMessage should be keeping a reference to its argument and keeping it alive. Do you know why it doesn't?
No idea. I really don't know what's going on behind the scenes but obviously the function the CPOW points to in the content process doesn't stay alive long enough since it causes dead CPOW errors when called.

This argument gets used as a CPOW on the other side. I expect that making it the responsibility of the sending message manager itself to keep that object alive wouldn't make sense - it has no way of knowing whether the other process is hanging on to the CPOW on the other side, so it doesn't know when the object can be GC'd on its own side. Whereas the consumer of sendAsyncMessage has a much better chance of knowing when to remove stale bits of data, or when to keep hanging on to them, like in this patch.
