Seeing something strange in dbpmda when checking out some new
MMV client code - the initial fetch failure is the issue...

(this is with /var/tmp/mmv/test as created by pcpqa/src-oss/mmv_genstats)
Any ideas? Is there meant to be an initial pmid lookup in the fetch case
in dbpmda or is the above behaviour as-expected?
