I failed to find in Boost.Exception documentation any note on how long is 
the lifetime of an exception object referred to by an exception_ptr. Also I 
failed to find it in the referred N2179 
(http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2007/n2179.html).

It seems logical to assume that the lifetime is not shorter then the 
lifetime of any exception_ptr object referring to the exception object. 
N2179 suggests possibility of use of smart pointer as implementation of 
exception_ptr which makes that assumption even more justified.

However I think that documentation should be explicit with this.
