The C++ Programming Language, 3rd Ed. section 14.10 includes

    "The standard exceptions are derived from [std::]exception.  However, 
not every exception is, so it would be a mistake to try to catch every 
exception by catching [std::]exception.  Similarly, it would be a mistake 
to assume that every exception derived from [std::]exception is a standard 
library exception: programmers can add their own exceptions to the 
[std::]exception hierarchy.

I hope that's of some use?  The quote doesn't really answer the question
of what BS _thinks_ should be the case, though... he just indicates how it
is.  (I included the [std::] because I can't otherwise easily indicate
where the italics were.)

P.S.  Some of the people in the threading discussion are really bad about
leaving a ton of quoted material around, which makes digests difficult to
read.  I'd appreciate it if people took the time to chop what isn't
relevant.
