Definitions can be made at run-time in other contexts apart from Global`.  
For example, AutoLoad packages make their definitions mostly in the  
System` context. Quitting the kernel removes all of these, as well as  
closing all open streams and MathLink connections, unloading  
LibraryFunctions, and so on. The command used to quit the kernel is simply  
Quit or Quit[].
