What it means is that "memory consumption" itself is a bit ill-defined. "ps", "top" and friends will tell you the amount of memory (physical or virtual) currently assigned by the OS to the process. It doesn't tell you whether the memory is "actually" in use by the program. Note that, in Python 3.3, sys._debugmallocstats() gives you fined-grained information about the object allocator. This excludes any blocks bigger than 512 bytes, though, since those are requested directly using malloc() and free(). ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue15635> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
