Reverting this one fixes the problem.
And adding --mca mtl ^mx to the command works too (Doug, can you try that?)

The problem is that the MTL component calls ompi_common_mx_initialize()
only once in component_init() but it calls finalize() twice: once in
component_close() and once in ompi_mtl_mx_finalize(). The attached patch
seems to work.
