Again it's a good idea to look at Zope's test drivers. For example,
implements an -L switch:
Keep running the selected tests in a loop. You may experience
In a debug build, that also automatically uses the TrackRefs class to break
down leaks by object type leaking, and by nature (leaking new objects vs
merely accumulating excess references without leaking new objects).
Beware overdoing it, though! Once the initial leaks found are plugged, new
ones are almost certainly caused by recent changes, and so much easier to
find. A ton of delicate leak-tracking framework becomes counterproductive
then. I think the Zope3 test driver (above) strikes a good balance.
