Intermittent build halt while installing Ruby gem pg_query

[jayvdb]

As of ~30 mins ago, the build has been halting:

Installing ethon 0.10.1
Installing pg_query 0.9.2 with native extensions

No output has been received in the last 10m0s, this potentially indicates a stalled build or something wrong with the build itself.
Check the details on how to adjust your build configuration on: https://docs.travis-ci.com/user/common-build-problems/#Build-times-out-because-no-output-was-received

The build has been terminated

Note, the problem may be "pg_query" or "scss_lint" or even something else.

I can't reproduce the problem by restarting the same build. the problem may be caused by TravisCI. :thinking:

https://github.com/coala/docker-coala-base/pull/115 was merged, after a few successful builds, so this problem is intermittent , or transient.
