Hi Brian,

I asked another developer. He says that the issue is that Open MPI
uses dl_open() to load MX after the application has started. In that
case, MX cannot use the regcache. He believes that there is/was a
change made to the MX MTL to provide a reference to MX.

Patrick may want to clear this up further and correct me where I
probably have led you astray. ;-)
