`glibc` has similar functions to monitor the memory allocation at the C level: `mallinfo[2]`, `malloc_stats`, `malloc_info`. The `mallinfo` functions can be called via `ctypes`. Provided your `glibc` has `mallinfo2`, I recommend its use. In order to use `malloc_info` from Python, you need a C extension. I have one implemented via `cython`. Let me know, if you are interested. -- https://mail.python.org/mailman/listinfo/python-list
