This really deserved a more descriptive comment. There's nothing wrong when fd 0 is reused by other streams. The problem was that because of a bug (arguably) in old glibc in CentOS6/RHEL6 freopen remapped stdout/stderr to fd 0 and 1. Which is, on itself, is not a problem either, but when mysqld forked other processes, these children had no access to stdout and stderr. it's too late to recommit now and, luckily, MDEV-7631 has all the information about this issue.
