Detailed Description

Specialization of StackContext for exception handling.

The supplied ``exception_handler`` function will be called in the
event of an uncaught exception in this context.  The semantics are
similar to a try/finally clause, and intended use cases are to log
an error, close a socket, or similar cleanup actions.  The
``exc_info`` triple ``(type, value, traceback)`` will be passed to the
exception_handler function.

If the exception handler returns true, the exception will be
consumed and will not be propagated to other exception handlers.
