<p class=MsoNormal>This is an example of why we have two votes - to give
everyone a chance to take a second look at the issues. I'll note that the
17-10 (counting no's and abstains together) is worrisome; while a majority vote
is the rule, a good standard will make a compelling argument for each feature.

<p class=MsoNormal>The process here would normally be to have a debate and then
the second vote. However, for MPI 2.2, we have the additional
requirements of limited scope of change to implementations - we didn't define
what that meant precisely (and that is a good thing), but there is a strong
argument that limited scope of change would require at least a majority of
implementations to agree that the change is minor. <o:p></o:p></p>

<br>
<tt>- Is likely to pass a simple majority vote, but does not carry the support
of the majority of MPI implementors, suggesting consensus has not been reached.</tt><br>

and therefore does not meet the intent of the MPI-2.2 process.</tt><br>
<tt>- Is not needed to fix any serious bug in the standard text or to solve an
issue that cannot easily be avoided by the MPI application.</tt><br>
<tt>- Does not offer any demonstrable optimization opportunities for
implementation or application, but may constrain future implementation
opportunities.</tt><br>

MPI-3 process, where more time can be spent assessing its impact.</tt></span><span
