[Twisted-Python] ThreadedSelectReactor

[Timothy Fitz]

Recently there have been some changes to ThreadedSelectReactor,
specifically that it is no longer being considered as a stand alone
reactor choice (for example, you will no longer be able to twistd
--reactor=threadedselect). This action is desirable since there's no
reason for it. As I understand TSR it's broken for that usage anyway;
however, I have been warned that TSR is completely broken and
shouldn't be used at all. What exactly and specifically are the
current problems or at least symptoms of TSR and is it truly broken?
