Gaah! I specifically asked Patrick and George about this and they

When I looked at that time, I vaguely remember that _both_ PMLs
were initialized but CM was eventually used because it was the last
one. It looked broken, but it worked in the end (MTL was used with
CM PML). I don't know if that behavior changed since.
I just tested 1.3rc4 with MX and it uses the btl by default. The
reason is the cm init lowers the priority to 1 unless the MTL that
loaded is psm, in which case it stays at the higher default of 30.
It's a fairly easy fix, I think. But the last time this was
discussed people in the group had objections to using the MTL by
default with MX.
