Ah, wonderful! Thank you!

I'm certainly glad it passed the 2nd time, as the failures were intermittent.

Re Appveyor and ruby-head (trunk), it is currently not 'allow-failure'. It will always return a build, but it may not be the most current, as it is tested. Said another way, if a build from yesterday passed, and subsequent builds fail, yesterday's build is what is used. From memory, I don't recall builds being broken for more than 24 hours.

But, from what I can tell, Travis does ruby-head builds once a day, and they are not tested. So, the possibility exists for a Travis build to be broken. Also, they currently aren't installing bundled gems.

Hence, for those reasons, Appveyor ruby-head can often be included in the normal build test result, but Travis may best be left 'allow-failure'. If it becomes an issue, feel free to change Appveyor (or ping me). Thanks.
