If you hop over to the original mercurial repository and check the
logs, you'll see that the daemonisation code hasn't been touched since
around 2010, so I'm not exactly surprised that it's not quite right. I
haven't personally used daemonisation in ages, what with upstart
working best without it.

I'll add it to the list for 1.5:

Yes, agreed. Another thing on the list :)
