All programs hold references to the program executable and its
libraries, and it looks like Upstart is no exception. I presume that
Upstart has some way of re-executing itself whilst preserving state in
order to relinquish the references to the old executables - this is
what "telinit u" does. (Without one, you'd run into some nasty issues
with upgrading it or any libraries it used.)
