Most of the issues I saw with our old code coverage setup were directly
related to them not matching our normal production builds. We saw
brokenness from the different compiler flags[1], timing out on test
steps[2] because they were running a monolithic build+test run, simply
failing to run tests because they didn't have an X DISPLAY set[3]. All
of these things were compounded by them not being terribly visible, so
nobody would notice they were broken for long periods of time.

Assuming the new setup more closely matches our existing builds I would
not expect as many problems to crop up. If we have someone committed to
owning the builds it probably wouldn't be that hard to keep them working.
