Again, is port 0 a valid port (given that you initialized it to -1)?
I know we haven't been doing a good job of domxml-from-native, but in
this particular case, can we also fix the command line parser to turn
'-device pvpanic' into the appropriate pvpanic device allocation?

Style. If you used {} for 'if', you must also use it for 'else' (I'm
still not sure how to enforce it by syntax-check, but it's on my list of
things that would be nice to have).
