-This test assumes that two lines that are output on different streams (stdout

-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.

+Subject: [PATCH] test: Fix a race condition
 
-Bug filed at https://savannah.nongnu.org/bugs/index.php?63651 to discuss a
-proper solution.
+The test suite does not differentiate between stdout and stderr. When
+messages are printed to both, the order in which they will reach us
+is apparently not guaranteed. Ideally this would be deterministic, but
+until then, explicitly test stdout and stderr separately in the test
+case itself. Otherwise the test suite fails randomly, which is a pain
+for distribution package maintainers.
