One more footnote. This article catalyzed the focus on memory leaks for me when I read it back in 2011: http://www.lshift.net/blog/2008/11/14/tracing-python-memory-.... It turned out that the memory leak was caused in a library which defined a specific method (del) that (was documented to) disabled garbage collection in some cases. You look here and the blame goes there, you look there and the blame goes here. Something is very wrong with software; who's in charge here?
