A lot of travis builds are timing out at the same shard.

tests/python/pants_test/engine/test_isolated_process.py::IsolatedProcessTest::test_integration_concat_with_snapshots_stdout <- pyprep/sources/a14d695d88ea487d28101d1c50e0b90e3d0e10bc/pants_test/engine/test_isolated_process.py 
No output has been received in the last 10m0s, this potentially indicates a stalled build or something wrong with the build itself.

If I run it locally, it only took a few seconds

./pants --owner-of=tests/python/pants_test/engine/test_isolated_process.py test
