There are situations, some discussed on this list, where doing gc 
'right' means turning off the cycle garbage collector. As I remember, an 
example is creating a list of a million tuples, which otherwise triggers 
a lot of useless background bookkeeping. The cyclic gc is tuned for 
'normal' use patterns.
