Glad to hear it, thanks for the feedback.  So far only about 36% of
our LDM sites have converted to 5.1.2, and very few have provided any
comments on any differences they have noticed.  I'm trying to put
together a couple of graphs for the PolComm meeting on the data rate in
products per second with 5.0 versus 5.1, depending on the number of
products in the queue.  This one summarizes things:

      Table 1. Measured rates of typical
   product insertion in a full product queue

   Products  Products/sec,  Products/sec,
   in Queue     LDM 5.0        LDM 5.1

      20000      130            300

      40000       66            243

      80000       40            230

     160000       20            210
