<p>
These interfaces are designed to make the stream interface
slightly easier to use from client code. This is done 2 ways,
first by make the exception environments optiional, and secondly
by providing slightly nicer semantics.

It is well worth using the bonobo_stream_client_write function
for any potentialy large writes, since this blocks the data into
sensible chunks. This is important, otherwise a single transfer is
attempted that will cause hassles in the CORBA stubs. [ NB. ORBit
tries to alloca a huge chunk of memory and SEGVs ].

This is a helper routine to write <em class="parameter"><code>size</code></em> bytes from <em class="parameter"><code>buffer</code></em> to the
<em class="parameter"><code>stream</code></em>. It will continue to write bytes until a fatal error
occurs. It works around serious problems in ORBit's handling of
sequences, and makes for nicer, saner protocol usage for
transfering huge chunks of data.
