This test takes 39 seconds on my machine even though it just runs a couple of fakesrc num-buffers=2 ! fakesink pipelines. Most of the cpu seems to be spent in libz, related to stack trace management. Use stack-traces-flags=none instead of stack-traces-flags=full until a better solution can be found. Might warrant more investigation in any case..
