quickest & easiest treatment would be the sys.setcheckinterval()
thing, which you can do just by setting the -i flag to 
Z2.py.  Edit your zope start script so that it looks something like:

exec /usr/bin/python \
     $INST_HOME/z2.py \
     -i NNN \
    ...

where NNN is pystones / 50.
How do you get pystones for your machine?
Run the pystones.py script which will be somewhere
like /usr/lib/python2.1/test/pystone.py
