			 * The highest existing pm nodeid is 1000. We run and import A's email
			 * Max existing pmid is now 1001. Second run skips A but imports B's and C's replies
			 * Max existing pmid is now 1003. Third run skips the three imported nodes and imports C's and A's replies
			 * Max existing pmid is now 1005. Fourth run skips the five existing nodes and run imports B's reply
			 * Max existing pmid is now 1006. Fifth run imports nothing, so the updates at the end of the group run and

			 *
			 * Often the parentid will be outside the current block. But since it will have already been imported, and the
