I could do something along following lines:

#include <iostream>
using namespace std;

void
unknown_exception_handler()
{
    try {
        throw;
    }
    catch( int i ) {
        cout << "int caught\n";
    }
}

int main()
{
    try  {
        throw 1;
    }
    catch( ... ) {
        try {
            unknown_exception_handler();
        } catch( ... ) {
            cout << "unknown exception\n";
        }
    }
}

and provide a way to configure unknown_exception_handler.
Dave, do you have something different in mind?
