What I'm saying is, there are two mechanisms for killing the daemon:
  1) losing the controlling terminal (shell could affect this)
  2) losing the X server (don't see how shell could affect this)

2) is the one I expect to be more robust and reliable. I don't see how 
it could be zsh-related, though anything is possible.

So I would first debug what's going wrong with 2), and only then try to 
figure out the probably-complicated-and-bizarre difference between bash 
and zsh with respect to 1). 1) probably isn't useful in this context anyway.

My theory is that 2) is somehow broken, maybe in dbus or maybe in the 
way it's run on the system; and that is causing 1) to matter, while 
usually 1) should not matter.
