FYI: that leak can hit you extremely hard depending on the code base, 
i.e. in Sage running the following two lines

for E in cremona_curves(range(11,10000)):
   print E.cremona_label(); ld=E.local_data()

goes from about 100 minutes down to 10 minutes CPU time and a leak of *8 
GB* is gone due to the above fix. The speed improvement is mostly due to 
the avoidance of garbage collection, but the cause of the above leak had 
eluded us for a while. So, thanks Robert for fixing this :)

  transformation code (Stefan Behnel, Robert
