Python: Start new terminal on Linux and wait for it to finish/exit

Same situation as my other question: Python: Start new command prompt on Windows and wait for it finish/exit except that I need it to work on Linux. If you don't feel like reading the other question: I want to open some new terminal windows and have each execute a command, and I want the parent python program to wait until all the terminal windows are closed. Doing: ``` os.system("gnome-terminal -e {command}") ``` Opens a new terminal window but the program doesn't wait. Using `p = Popen()` and `p.wait()` doesn't work because the gnome-terminal command completes instantly.
