This program should *not* be installed suid/sgid root or
any other user with special privileges. It's known to have
repeatedly compromised security and it's one of the first
first binaries that I chmod 755 after installing a new Linux
system. By not making it suid/sgid you force the program to
generate ~/.xlockrc where the screensaver password is stored.
I believe this is secure enough, as the file is chmod 600
and enables you to set a different password [not the system password]
on the screensaver.
