Nice read, even though I haven't written any Python in a long time. Memory management in modern OSes is very complicated and there isn't a simple answer to "how much memory is my process using exactly". [1] Memory growth / usage isn't usually something to worry about unless memory growth is constant under load and/or OOM killer kicks in.

Also consider that `heapy` will probably only report on objects created by your Python code, and not any memory taken up by native code in the interpreter itself or any shared libraries.
