Description

This was noticed during registry client test( please see MESOS-3773).A brief summary :

1. open a file with flags " O_WRONLY | O_CREAT | O_TRUNC | O_CLOEXEC" and mode "S_IRUSR | S_IWUSR | S_IRGRP | S_IROTH)",

2. Call write(fd, string).

This causes junk to be written every once in a while to the beginning of the file.
