I've filed ticket #320 for this: https://trac.mcs.anl.gov/projects/mpich2/ticket/320

I've changed this in a way that should be more palatable to you guys.   
Take a look at r3629 and let me know if that will work for you: https://trac.mcs.anl.gov/projects/mpich2/changeset/3629

It needs a bit more testing before I'd be comfortable releasing it,  
but it does pass the mpich2 test suite at least.

I'll see if I can get this applied within the coming week.  Thanks for  
the patch.
