profiling

We have ~300 celeryd processes running under Ubuntu 10.4 64-bit , in idle every process takes ~19mb RES, ~174mb VIRT, thus - it's around 6GB of RAM in idle for all processes. In active state - process takes up to 100mb of RES and ~300mb VIRT

Every process uses minidom(xml files are < 500kb, simple structure) and urllib.

Quetions is - how can we decrease RAM consuption - at least for idle workers, probably some celery or python options may help? How to determine which part takes most of memory?
