   I believe it to be the right place.

   There isn't much documentation on a site, as far as I know, but you can start
by going in the ZODB code and read in the interfaces.py files the docstring of the
interfaces, that defines the API. There is lot of information to be found there.

   I think he meant this method on the transaction object (that you can get with
transaction.get):

       def addAfterCommitHook(hook, args=(), kws=None):


   You will find more information about this method in the interfaces.py file of the
transaction package.
