<pre style="margin: 0; padding: 0; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">When processing a 212MB refs file, refcounter.py used over 3GB of RAM. This caused swap thrashing and temporarily froze my system. The included patch makes the following memory optimizations:
* skewed and finished object lists are only populated if not disabled
* lines are saved to each object as the final output line
Saving the whole lines in output format seems to reduce memory usage by 80-90%. Ignoring finished/skewed objects caused an additional reduction of about 75% on my system.</pre>
