can you explain more -or show code- about that stuff? i'm curious :)

useful! i've added a scons option, reconfigure this way:
scons configure optimize_and_lose_precision=yes

however i'd like to see some valgrind numbers. since we now have the
FreewheelingNetworkPlayer tests it will be very easy. anyone volunteers?
btw, david, is efficiency-guardian app kind-of ready to be used?

commited in revision 9969.
i've tested networkeditor smstransposition example in both
configurations and saw no appreciable difference jack cpu load was
oscillating from 30 to 50% in both cases
