On openSUSE's build system, I sometimes see a test failure from the above test on x86_64. Trying again usually makes the test pass.
I'm not sure if we have a race in the test, but the result looks identical as if tail(1) would have been started with the (test-only) option ---disable-inotify (thus not being able to "revert to polling" as it started in this mode). Any idea? Have a nice day, Berny
