Why do you think so? I'd expect an exception instead of potential data
loss (due to not being to able to post the actual data to the worker).
I'd be happy to filter the "r" out of the list if I need to, but I'd
hate to try to figure why *some* of the data I was posting does not show
up at the worker. Obviously, if I know that I cannot post "r" and I
don't want to do the filtering myself, it would be nice to have an extra
parameter for postMessage() telling that it's okay to drop some data if
it cannot be transferred but that should not be the default. However, I
would consider that a special case and API could do just fine without
