With Django all state is in the database(unless you've setup cookies).
There's no guaranteed persistent process. You'll need to use whatever
periodic scheduler Dreamhost gives you (cron, other?) to run your
background tasks as separate python scripts. Here's an example:
#!/usr/bin/python
import sys
# This is my django model that I want to do something with
from mfg.bundle.models import Bundle
try:
bundles = Bundle.objects.all()
for bundle in bundles:
bundle.do_something()
except:
print "Something went crazy wrong!"
sys.exit(1)
sys.exit(0)
