Ad 1: I don't really control child process exit here. Net::Server does.

Ad 2: That would be the solution if you wanted to create an object in a parent and have only the parent DESTROY it. (like if you have process shared resources). But that's not the intention or the problem here. I *want* each process to execute DESTROY - but only once for each Perl object. ... and this solution still relies on DESTROY being called only once in each process. This is not the case here. ... it's a little different whether it's the parent or the child which calls DESTROY twice.
