Twisted 8.1.0 prerelease 2

Hey all, I've put out the second prerelease of Twisted 8.1.0. This release includes a number of bug fixes, including for some unfortunate regressions in 8.0.1, as well as a few features.

• Trial's performance was improved
• Fixed a bug where Failures wouldn't be constructible involving Pyrex
• Fixed a couple of reactor re-entrancy bugs introduced
• Fixed the conch.insults bug where gnome-terminal wouldn't scroll when output reached the bottom of the screen.

And a bunch of other miscellaneous fixes. Please download this prerelease and give it a try with your applications.
