This line is a severe bug, at least in my current build: In response to a node responding to a refresh request, this line sends the node another refresh request! (As far as I can tell, the line should just be removed. Not sure why it's there.)

It was flooding my logs with refreshes, so fast the rest of the network never could fully initialize. Basically borked my network. Commenting the line out fixed it. (Could instead have disabled it in node.py, but I assume it is correct there and the bug is in network.py)

I'm not sure why everyone doesn't run into this -- maybe using an older openzwave library that has broken refresh requesting or something?

(I don't grok git well enough to submit a patch but it's just one line that needs to go...)
