If a non-GUI process launched from an .app bundle calls certain OS  
APIs, OS X automatically upgrades it to full GUI status. e.g. Py- 
appscript has this problem, despite having no need for a Window  
Manager connection itself: it calls Process Manager, which is one of  
the APIs in question, and the python interpreter is packaged as  
an .app, so you get a bouncing Dock icon any time you use appscript  
from the command line. By comparison, Ruby's interpreter isn't  
packaged as an .app, so using rb-appscript won't automatically GUI-fy  
your ruby process.
