Maybe someone can help me from having to think too hard.

Let's say I want to max my system limits.  I can say this:

    % mpirun --mca opal_set_max_sys_limits 1 ...

Cool.

Meanwhile, if I do this:

    % setenv OMPI_MCA_opal_set_max_sys_limits 1
    % mpirun ...

remote processes don't see the setting. (Local processes and ompi_info are fine.)

Bug?  Naively, this looks "wrong."  At least disturbing, in any case.

This is with v1.5.
