Just to go in circles once more ... PM_CONTEXT_LOCAL is only ever going
to work for the (DSO) PMDAs that have been "Install"ed on the local host
because this is the only way to get the correct PMNS installed as well.
So I think the using pmcd.conf model would work just fine ... and
Nathan's right we don't need to extend the pmcd.conf format -- if you
are a DSO PMDA defined in pmcd.conf then by default you're available via
PM_CONTEXT_LOCAL, end of story.
