It might for some thrown values in some implementations.  It would 
definitely mess with reported exception ordering wrt actually uncaught 
exceptions... and in cross-realm cases has problems in terms of which 
realm's error-reporting machinery should be invoked.

Though I guess any API here has that last problem to some extent, 
actually.  We might be able to hide it under the hood if the callback 
that threw is passed to the API along with the exception.
