Better Prevent poopin' on OS X

Original prevent poopin' unmounts servers you are connected to.

Go to System Preferences > Security & Privacy.
Set 'require password immediately after sleep or screen saver begins'.

Drop this into your .bash_profile/whatever:

alias poopin='open -a /System/Library/Frameworks/ScreenSaver.framework//Versions/A/Resources/ScreenSaverEngine.app'

It just starts your screensaver.
