On two machines (Linux/sparc64 and Linux/riscv64, real hardware, Gentoo) I see reproducible test failures of tail/retry. See attached log files.
I do *not* see these failures with architectures in the same farm (matoro.tk). I also do *not* see these failures in QEMU VMs with a local (surely ext4) file system.
