Some of the test_decoding regression tests are unstable due to modifying a sequence. The first increment of a sequence after a checkpoint is always logged (and thus decoded), which makes the output unpredictable. The runs are usually much shorter than a checkpoint internal, so these failures are rare, but we've seen a couple of them on animals that are either slow or are running with valgrind/clobber cache/... Fixed by skipping sequence decoding in most tests, with the exception of the test aimed at testing decoding of sequences.
