I certainly don't confuse them (GC wouldn't be very interesting if the 
two were the same), and as I understand it there exist very few GC 
implementations that _guarantee_ responsiveness over a long time period. 
This effect gets a lot bigger as memory usage and reference mutation 
rate grow. It is very easy for a sufficiently big Java application, for 
instance, to get responsiveness problems.
