As mentioned on IRC, I suspect it will. However, at first glance, I
think the logic itself is fairly sound (blocking to wait for it seems
reasonable in the circumstances) and the --no-block argument should work
around things OK (if it weren't all hardcoded via the legacy initscript
of course!)

I'll try and get a proper answer for you tonight as to whether it was
that commit that caused this issue to bubble up to the surface.
