Comment(by ramey):

 Note that it has always been my idea that serialized data
 could be embedded into another stream.  I think the question
 you've raised touches upon this.

 note the comment at line # 174 of basic_binary_iprimitive.hpp

 // some libraries including stl and libcomo fail if the
 // buffer isn't flushed before the code_cvt facet is changed.
 // I think this is a bug.  We explicity invoke sync to when
 // we're done with the streambuf to work around this problem.
 // Note that sync is a protected member of stream buff so we
 // have to invoke it through a contrived derived class.

 this suggests that the "sync" was only added in response to
 some other difficulty.  Take another look at this problem
 and tell me what you think.
