This enable all programs to have access that are using unix domain
sockets to not need the MIT-MAGIC-COOKIE stored in the .Xauthority file
in the users home directory so any user can open a program on that
display. xhost +localhost adds all programs from localhost using tcp
connections instead. DISPLAY=:0 causes a program to use fast unix
domain sockets where DISPLAY=localhost:0 causes a program to use slow
tcp sockets instead. tcp sockets are really only needed for remote
connections and xhost +localhost won't allow any local programs to
access X unless they use tcp, not unix. See my first response for more

I sense much NT in you.
NT leads to Bluescreen.
Bluescreen leads to downtime.
Downtime leads to suffering.
NT is the path to the darkside.
Powerful Unix is.
