Actually I think you can have a space leak without a time leak.  For 
instance if every time around the main loop I cons data onto a linked 
list that never gets freed then I have a space leak.  If the list never 
gets used (or more realistically, if the program only ever uses the 
first N entries) then there is no time leak.

I agree that a time leak implies a space leak though.
