It's normal, IIRC. It's called with different arguments, once for each db
thread and once with None. When I use it (to do some cache flushing after the
db commits), my function looks like this:
def oncommit(_db):
"custom_commit callback: commit, then flush the cache"
if _db is None: # after all commits
flush_active_channels()
else:
_db.commit() # not called for Google Datastore
