<p><font size="2" face="sans-serif">While the implementation I'd be making would probably not distinguish between MULTIPLE, SERIAL, and FUNNEL, I still believe that there are implementations that do benefit from using a lesser threading model and would still be able to use helper threads. I think it is short-sighted to rule out those modes for helper threads.</font><br>

Convincing the Forum about that is an uphill battle, AFAICT (not sure <br>
which way I'll vote on that, either). I'd like to not add that in the <br>
initial proposal. If you like, we can create a second proposal chapter <br>
(like what we are doing in the RMA WG) with these "additional changes" <br>
which will be good to have, but not critical.<br>
