As an example, I've written an ASIO-based application that makes use
of callbacks where one of the arguments is an exception_ptr. If the
exception_ptr is not null then it contains the exception that occurred
during the requested operation. It can run with a single thread and
the exception transporting would still be useful. Before I used
exception transporting I was passing a status indicator which was not
nearly as nice.
