These close a couple of issues with mdmon.

As foreseen it does actually fail...

someone might remember my flaky dual boot system with imsm array
it crashed again, badly
result
mdmon is still running from ALT_RUN, since / is corrupted and cannot be
mounted read-write
but mdadm command looks for mdmon only in VAR_RUN
so a new bunch of patches is due.
these apply over the two preceding patches

Rather than adding complexity to the code, would it not be easier to just mount a tmpfs on VAR_RUN since it is ephemeral anyway and is not valid across boots? It seems more reasonable to put the exception handling in the system with the exception than in production code.
