travis is very slow atm, so we're not running 1.3 builds for
a while.

Seems to be too unstable?

travis is experimenting with a setup using KVM, instead of
independently provisioned VMs. It promises to be much faster. We're
testing it out.

from irc:

<jbenet> Any idea why this job isn't finding Go?
  https://travis-ci.org/jbenet/go-ipfs/jobs/49296465 --
  we havent had problems for a while and now lots of
  builds fail like this.
<•meatballhat> jbenet: still around?
<•meatballhat> jbenet: the `release` name was something specific to
  gvm. As there is no `release` tag in the go repo, it's no longer a
  valid target. What you probably want is `1.4.1` or `master`.
<jbenet> meatballhat: ah thank you
<•meatballhat> jbenet: np, sorry about the switchup!  gvm had been
  woefully undermaintained since August, so we were long overdue in
  replacing it.

the travis docs say the env flag TRAVIS=true but, i want
to make absolutely sure. explicitness leaves less room for
error.

Go 1.2 is no longer supported (we use sync.Pool).
