// NOTE (t.heintz): This is very evil to do, because the TBufferedTransport may swallow bytes, which
// are then never written to the underlying transport. This happens precisely when a number of bytes
// less than the max buffer size (512 by default) is written to the transport and then flush() is NOT
// called. In that case the data stays in the writeBuffer of the transport, from where it can never be
// accessed again (for example through read()).
//
// Since the caller of this method does not know about the wrapping transport, this creates bugs which
// are very difficult to find. Hence the wrapping of a transport in a buffer should be left to the
// calling code. An interface could used to mandate the presence of the putBack() method in the transport.
//
// I am leaving this code in nonetheless, because there may be applications depending on this behavior.
