I take it travis doesn't object to building 4 versions of emacs from

I don't know why they would. There are many open-source projects with
much higher computational demands using Travis' free service. There are
also many projects doing the exact thing proposed in this patch:

How long does that take?
About 2-4 minutes for the tagged releases and 6 minutes for the
snapshot. You can see the times yourself in the build logs for the
Travis results of my fork:
https://travis-ci.org/CyberShadow/notmuch
The figure you're looking for is the execution time of the "make -f
emacs-travis.mk install_emacs" command, displayed on the right-hand side
in the log.
I'm not very happy about downloading and running code from a third party
during our test runs.
Why do you think so?
Consider:
- You are already relying on a third-party here (Travis). They run a lot
of code specific to their testing platform on their systems.
- The code (emacs-travis.mk) is specific to Travis. It is not part of
the notmuch test suite, just the Travis configuration which runs it.
- Using emacs-travis.mk in this manner is how many Emacs packages run
their tests:
