Noted first, this is in any case not a mintty issue as mintty updates
the title whenever it receives the respective escape sequence. The
scenario sounds weird, however. Is the background process continuously
sending title escape sequences? But 'emacs &' looks like you're starting
a GUI instance of emacs, right? So why should it?
