It's not a question of broken; making a lot of programs (like mine for
instance, lxdoom) suid could be a security risk. The window Wichert talks
about is a window of opportunity where a binary is installed suid and
can be exploited, before the system administrator decides (for whatever
reason - bugtraq or otherwise) to remove the suid bit. That's why I ship
lsdoom by default as not suid, and then enable the suid bit later at the
request of the sysadmin.
