Did you look at my patch or the demonstration yet? I posted all the details this afternoon. 

I tried very hard to support verbosity suppression in a reasonable way at runtime. 

Do you really want an MPIX call that is equivalent to setenv("<see patch>")? Is the extra code worth it? (These are serious questions.)
