If you do not have Twisted commit access, feel free to create a wiki page linked from this one and add docstrings there.  If you write a docstring, please remove the name of the object it is for from the relevant Undocumented wiki page.  Likewise, please remove the names of any objects which actually do have docstrings -- these lists are mostly automatically generated and there may be mistakes.
