Maybe that is the 4th alternative I couldn't think of earlier :-). I also 
thought of one more: emailling the system administrator. Useful on servers.

I hadn't thought of such issues. Is uncaught_exception() implemented in all 
modern compilers? Falling back on one of the other methods when it returns 
true instead of throwing an exception avoids some of the problems.
