fsync(): be prepared to see EINTR
Some platforms, like NonStop do not automatically restart fsync() when interrupted by a signal, even when that signal is setup with SA_RESTART. This can lead to test breakage, e.g., where "--progress" is used, thus SIGALRM is sent often, and can interrupt an fsync() syscall. Make sure we deal with such a case by retrying the syscall ourselves. Luckily, we call fsync() fron a single wrapper, fsync_or_die(), so the fix is fairly isolated. Reported-by: Randall S.
