[MPICH2-dev] Two mpich2-1.0.3/mpiexec issues

[Rusty Lusk]

Hi Dmitry,

    Thanks for pointing these problems out.  The first one was already
fixed in our development version.  It may be that we have already fixed
the second one as well, but I would like to make sure.  Can you send me
an example invocation of mpiexec that illustrates the problem, so that
we can attempt to reproduce it?  

Thanks,
Rusty Lusk
