This can't work. Are you sure that you checked that perl destroys the 
objects when going out of scope? I can't believe that. You won't see a 
memory leak at the end as perl destroys then ALL objects but it does not 
when going out of scope.

Just add a warn to the DESTROY subroutine and check your log. Perl 
should call DESTROY on the object in each loop run of pvestatd. But with 
your suggestion it does only at the end when killing the daemon.
