I'm confused with closing terminal applications in OS X. Why processes are not killed after closing terminal app? For example I call python interpreter then close it with ctrl+z and when I try to close terminal it asks me about running python processes. Sorry for Russian in the screenshot but you can see 2 python processes(I called it two times).
It's very annoying especially when you are working with serial port using minicom for example. You have to kill process manually after each call. Is there a way to kill them automatically?
