gnome-shell/src/gnomeshell-taskpanel.c
Colin Walters 70a3434b5a Add a panel containing tasklist to bottom screen
This is implemented as a separate process, since creating and running
toplevel windows from inside Metacity has issues.

We now grab a DBus name, and exec the child process.  The child monitors
our name to know when to exit.
