To be honest, I'm out of resources to implement such a change.
LAM is in maintenance mode -- we're putting all of our effort into Open
MPI (which is why it's taking me a while to fix the IMPI bug in LAM :-(
). Don't get me wrong -- it's not that I don't want to fix it, or
don't want to implement this feature, it's that I simply do not have
enough cycles to do so. :-\
