// http://www.drdobbs.com/184401357:
// A slightly more serious concern is that the virtual functions in a
// class that's derived from streambuf might throw exceptions;
// perhaps, for example, a user-defined class for network I/O might
// throw an exception when the underlying connection has been
// lost. High-level istream and ostream functions will catch those
// exceptions and translate them into an error state within the
// stream (that’s one of the reasons that seemingly innocent
// functions like istream::get are so complicated), but if you’re
// working with stream buffers directly there’s nobody to catch
// exceptions for you. If you work with stream buffers, you should
// make sure that your code is exception safe.
