thanks for the very kind words. I cherish them all the more coming from you.
BTW, it didn't tkae me all that lonk to perform the test, grep and

ago when I did a more elaborate investigation of the impact of different
dfmrc setting on the performance of full scans - and their impact on
concurrent single reads.
