3.8.0 Release Preparations

Now that it's Sunday. I would like the master branch to remain "mostly"
frozen. "Mostly" meaning that if there's something trivial (e.g. a typo, a
codingstd issue, additions to documentation, etc.), I won't mind if you
commit those changes so long as you make me aware. Cleaning those little
nooks and crannies at the last minute are fine by me. Only after Monday
night though (all of Tuesday) do I want people leaving the master branch
completely alone. That's when I'm going to be cutting the release (with the
help of my new little auto_release.pl <http://nopaste.snit.ch/81846> script
- a work in progress but still something I'll include in the release for
future managers).

So far, things appear to going well. The only failures on 'fulltest' are
codingstd issues which I'm currently working on at the moment. The only
other potential problem is that fact that my public SSH keys still do not
work on our OSUOSL FTP server. I've opened a support ticket for this so
hopefully it will be resolved before Tuesday night. Other than that, this
shouldn't be a problematic release.

Actually, I ran into other problems yesterday with t/dynpmc/select.t too.
Apparently, it was leaving behind a README2 file. I was able to fix it with
a simple call to unlink() but it also forced me to look into the
experimental nature of select().

It obviously needs to be tested but if the behavior is not defined on
MSWin32-related systems, I'm not sure that we really have any other options
other than simply skipping them. I do think we need to add socket-based
tests though (not just for MSWin32 but all OSes). I'll do some research and
look at how the IO::Select handles its tests but even so, I'm not sure we
have enough time to 1) add those tests and 2) have them thoroughly tested
and passing on several platforms before Tuesday night.

This has been a long-standing issue and so I agree with you in that it
definitely needs to be addressed now.
