Well... I removed 3 of the exit you spot. Think about asserts, they
exit application if they don't pass. I agree to remove any print
statements and I removed a lot. There are however situations when even
the os kernel "exit" (that is stop the entire system). In this case if
an internal handler returns any values which are not coded to return
some nasty things happen and I don't see any point in keeping going.
