Uh.. that's not been my experience.  I was a bit unclear in my
description, though.  Until maybe a week and a half ago I found the
Travis build was fairly reliable, though there were occasional
transien failures.  Now, essentially every Travis build is failing for
me.  Specifically most of the first dozen or so of the batch of build
configurations on Travis fail (that's "X" not "!").  These seem to be
transient failures in the sense that if I rebuild enough times they'll
eventually pass, but unlike earlier when the builds would suceed most
of the time, they now seem to succeed at best around 1/3 of the time
(that's ~1/3 of the time for each configuration sub-build, so with a
dozen or so apparently affected that means a complete passing build
essentially never).

See for example https://travis-ci.org/dgibson/qemu/builds/263312174
where 5 subbuilds have failed (which is relatively few).  In each case
the failing error seems to be something like:

ERROR:tests/vhost-user-test.c:807:test_connect_fail: child process 
(/i386/vhost-user/connect-fail/subprocess [55883]) failed unexpectedly

Seems to be i386 in some cases and x86_64 in others.
