Wearing my SELinux hat on, I find that daemons not closing file
descriptors when forking children result in a large number of AVC
denied messages. Of course, sometimes there are legitimate reasons for
not closing the descriptors (and these use cases can then be explicitly
allowed in the security policy). Most cases, though, it seems like the
authors are just being lazy.
