This test assumes that if a child process writes one line to stderr and
then another line to stdout, and stderr is redirected to stdout, that
the order the lines will be read is stable.

This isn't the case and occasionally the lines will be read in a
different order.  Change the test to ignore line ordering.

+This test assumes that two lines that are output on different streams (stdout
+and stderr) will be read in the same order, but thanks to buffering that may not
+be the case.
+
+Change the expected lines to be regexs that each match both expected lines, so
+the test always works no matter the actual order the lines are read in.
+
+Bug filed at https://savannah.nongnu.org/bugs/index.php?63651 to discuss a
+proper solution.
