Really? How could your clients not notice 60 GB of memory
usage unless they are running some kind of mad-dog insane
top-of-the-line hardware? (Got Benjamins???) Of course, in
the case they are not DARPA scientist supported by a
viturally unlimited supply of tax dollars provided by the
endless toils of American slave-bots, how could they ignore
the thrashing? o_O
