Run on

[brynmawr1]

I'll just add my 2 cents.  I don't mind or even notice it as a run on sentence.  I'm not sure there is really such a thing in poetry given how it is written.  As Wjames pointed out, the line breaks provide enough pauses, though subliminal, to remove any tedium.  Also, the fact that poems are often written without any punctuation to good effect makes the concern about something as prosaic as a run-on sentence moot.
