Some additional data:

I'm using Django 1.1 on Fedora11 with sqlite backend. I get the same
kind of spiking of memory usage if I just enter:

>>> Person.objects.all().delete()

Memory usage continues to grow, and it doesn't seem to be able to be
garbage collected. What could cause this? Anything I can set or issue
to make Django clean up/use less  memory? I am running out of memory,
just deleting the data! Something seems to be very wrong...
