 Dear Ion,

 I am planning to use your message_queues in new project and like it.
 However, I find the exception messages not very useful.

 One problem may be that in interprocess/exception.hpp, the
 constructor
     interprocess_exception(error_code_t ec = other_error )
 always sets the m_str value (which is returned by the what() member
 function) to the same phrase
     boost::interprocess_exception::library_error

 Better would be something that is appropriate for each type
 of error, for example:
     message_queue receive: buffer_size (1) < max_msg_size (100)

 There are only a few places where exceptions are thrown in
 message_queue.hpp. Would it be possible to have for each of them more
 useful error messages for the what() strings?
