Done. It looks like there is still plenty of memory leakage, but there are improvements, and the huge list of uncollectable garbage with tkAgg is gone. I also made memleak_gui.py more flexible with arguments. For example, here are tests with three backends, a generous number of loops, and suppression of intermediate output: python ../unit/memleak_gui.py -d wx -s 500 -e 1000 -q uncollectable list: [] Backend WX, toolbar toolbar2 Averaging over loops 500 to 1000 Memory went from 29316k to 31211k Average memory consumed per loop: 3.7900k bytes python ../unit/memleak_gui.py -d tkagg -s 500 -e 1000 -q uncollectable list: [] Backend TkAgg, toolbar toolbar2 Averaging over loops 500 to 1000 Memory went from 29202k to 31271k Average memory consumed per loop: 4.1380k bytes python ../unit/memleak_gui.py -d gtkagg -s 500 -e 1000 -q uncollectable list: [] Backend GTKAgg, toolbar toolbar2 Averaging over loops 500 to 1000 Memory went from 29324k to 31131k Average memory consumed per loop: 3.6140k bytes So, this test is still showing problems, with similar memory consumption in these three backends.
