Hmm, okay. That seems unlikely, but I think we can guard against this.

I decided to tackle this from a different directly, though. I've
solved this in the upstart script that runs pollen, by testing that
$DEVICE is in fact a character device. This involved a couple of
other changes (which are useful/necessary), including making the
DEVICE itself an argument to the pollen server itself.

Committed revision 171.

As a side note, the Pollen argv handling could be more robust. For
now, it's documented in the manpage that all of these arguments are
required.
