The description 'object-oriented' may apply to both programming
languages and operating systems.  However, creating an interface
between an object-oriented programming language and an object-oriented
operating system is not necessarily a straightforward task.
Chrysalis++ is a C++ interface to the Chrysalis operating system for
the BBN Butterfly Parallel Processor.  The development of Chrysalis++
highlights strengths and weaknesses of C++ and the problems of adapting
a language based on a conventional memory model to a shared memory
parallel processor.
