+Notes:
+- Using a real file is often faster (but less convenient).
+- There's also a much faster implementation in C, called cStringIO, but
+ it's not subclassable.
+- fileno() is left unimplemented so that code which uses it triggers
+ an exception early.
+- Seeking far beyond EOF and then writing will insert real null
+ bytes that occupy space in the buffer.
+- There's a simple test set (see end of this file).
