Use the KWSys Process "MergeOutput" option to give each test child process the same pipe for both stdout and stderr. This allows natural merging of stdout and stderr together instead of merging on arbitrary buffered read boundaries as before.
The test expect sub-test not to run in parallel.
This option tells ctest to run each test N times until the test fails or the N times have run. This is useful for finding random failing tests.
