For clarity this is triggered by the kernel sometimes exposing an EIO
where we are expecting EOF.  This tickles an issue with libnih which
accumulates input in a read until EAGAIN loop, and dumps (arguably
erroneously) its entire pending buffer when it sees an unexpected error.

Bug description:
  As you see in the history in https://jenkins.qa.ubuntu.com/job/vivid-
  adt-upstart/?, upstart's test fail almost all the time, on

  ok 53 - with single line command writing fast and exiting
  not ok 54 - with single line command writing lots of data fast and exiting
   wrong value for bytes, expected 3145728 got 3018027
   at tests/test_job_process.c:3886 (test_start).

  FAIL: test_job_process

  Sometimes they succeed on one architecture, and with lots of luck on
  both, but this is way too flaky to be an useful test. This keeps
  blocking the propagation of other packages from -proposed.

  This was most likely triggered by the kernel update from 3.18 to 3.19.
