Comment 5 for bug 1237710

I was looking at this (on desktop) a couple of days ago - before getting sidetracked by something more urgent.

It is an interaction with another test (or tests) and I could reproduce by running

    bin/acceptance-tests --gtest_filter=ServerShutdown*:TestClientInput*

I suspected that the "stale" acceptance test instance was the cause, not result of the failure reported.
