The only reason I said that is that I know how constant-mass flow systems
work, but I don't know how constant volume fraction systems work...and I
didn't want to pre-suppose the latter were necessarily more reliable than
electronics.  I didn't intend to compare the two non-electronic o2 control
systems....
