/** is a stream which allows writing the data of persistent objects.
	
	<p>Implementations of this service must fulfill the specifications of the 
	<type>DataOutputStream</type> service; futhermore, the stream needs to be chained to a 
	<type>XMarkableStream</type>. Therefore, it also provides the <type>XMarkableStream</type>
	interface, but it delegates the calls to the chained object.
	The written objects are held until this instance is destroyed.
	The references to the objects are written as four-byte integers 
	and begin at 1. Data format is written: </p>
	<pre>
	short   InfoLength
	long    ObjectReference // 0 indicates no object
	UTF     ServiceName     // length of 0 indicates this is only a reference
	long    ObjectLength    // 0 if it is a reference or no object, otherwise the len of the object data
	Object  ObjectData      // the data of the object
	</pre>
	
	@garantees
	<ul>
		<li>-thread safe </li>
		<li>-allow buffer size is 2 ^ 31 -1 </li> 
		<li>-maximum object reference identifier is the number of objects.  </li> 
		<li>-object reference identifier 0 indicates no object </li>
