How does the Python interpreter maintain the state of a generator during 
calls to yield?  Evidently the entire state has to be restored from 
wherever it's being kept and plonked back onto the current stack.

Perhaps this is a slightly stupid question, but it's more interesting than 
the other "What part of ... do you not understand?" stuff.
