One way, if you are afraid the change from 7.3 to 8.1 would
corrupt/break the ensim cp app, would be to compile your own copy of
8.1, installing it alongside 7.3 (in a different directory), running
on a different tcp/ip port, and run the two in parallel.  7.3
handling the ensim program, 8.1 handling LSMP.
