Well the exit code that was used for the exit function call is stored
in memory somewhere. The exit function doesn't just immediately
terminate the program. A whole bunch of other stuff happens first,
i.e. resources freed, exit handlers called, etc.
That variable has to be stored somewhere so that you end up with value
1 when the process finally ends.
