Subject: Fixed a problem with mysqld_multi log file. The default is now
 datadir/mysqld_multi.log, if doesn't exists or is not writable, then
 /var/log/mysqld_multi.log, if does not exists or is not writable, then
 /tmp/mysqld_multi.log, but only in case the file does not yet exists in /tmp.
 Otherwise log will be disabled, unless user explicitely sets it with an
 option.
