Re: Jython 2.7.0 final soft launch

This change in test_sort behavior is due to an update in Java 8, as Jeff
mentions.

For both OS X 10.10.3 and Ubuntu 14.10, I have now upgraded my Java 8
versions to 1.8.0_45 from an earlier release (1.8.0_05-b13 on Linux, didn't
capture on OSX), and I can now reliably reproduce what Jeff is observing.
Prior to this, I was running `watch bin/jython -m test.regrtest test_sort`
for an extended period of time.

Meanwhile on Windows 8.1, I'm currently running the earlier build of
1.8.0_40-b26, and not seeing this problem.

However, the failing test is seen in "insane comparison function" that was
created to attempt to segfault CPython; I believe the latest build of Java
8 is now do more checking here, since we rely on Java for the
implementation of sort. Note the test does not fail if run with --verbose,
because it's actually reporting extra output.

Conclusion: we may have to adjust the test in 2.7.1, but not something to
delay the release on.
