Once I had a strange memory leak in a long running process. This 
turned out to be a problem of objects filing up in gc.garbage 
I think those objects where also not reachable through 
gc.get_objects() - as used by the script above. So be aware. Maybe 
you've got the same motive for your counter.
I was somewhat stunn seeing, that obviously almost any serious 
bigger app needs to watch and handle/free the gc.garbarge list "by 
hand", to remain stable.
