`System.in` and `System.out` are both
[`PrintStream`](http://hg.openjdk.java.net/jdk7u/jdk7u/jdk/file/8108ffe38ccb/src/share/classes/java/io/PrintStream.java)s.
That class already is error prone like mad (autoFlush yes or no, checkError
instead of throwing exceptions, etc.). It internally creates a `BufferedWriter`
used for writing characters. I haven't found anything in the JDK flushing those
buffers so it seems this is up to the application. I am quite sure that closing
those streams manually is correct. That's what you would do in a C application
as well.
