[ZPT] Batching SQL results

[Andreas Jung]

You are strongly encouraged to use a batching framework e.g. PloneBatch 
which also
runs in a plain Zope environment without Plone. It makes your life easier 
and you don't
have to care about such issues you are asking about. Search on plone.org 
for details.
