In general, it is not a good idea to explicitly commit a transaction:

  If after the "commit" a "ConflictError" occurs (which is not
  that unlikely when you modify the ZODB), then the
  publisher will retry the requests.
  This means that the transaction you already committed
  is performed again.

In your case, this may not make a problem, though.
