No, but given that the user agent may terminate either way (including
without exception), it is better not to throw, especially as this it
is implementation-dependent. You only want to throw if it's traceable
to a clear developer error, here it's not at all clear why.

Also, I think the IDL should say "(unsigned long or sequence<unsigned
long>) pattern"

So why does that spin the event loop? Having this method be
synchronous seems really bad.
