o Allow privileged processes in jail() to override sticky bit behavior
on directories.
o Allow privileged processes in jail() to create inodes with the
setgid bit set even if they are not a member of the group denoted
by the file creation gid. This occurs due to inherited gid's from
parent directories on file creation, allowing a user to create a
file with a gid that is not in the creating process's credentials.
