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.
