DESCRIPTION

22       Perl's global destruction is a little tricky to deal with WRT
23       finalizers because it's not ordered and objects can sometimes
24       disappear.
25
26       Writing defensive destructors is hard and annoying, and usually if
27       global destruction is happenning you only need the destructors that
28       free up non process local resources to actually execute.
29
30       For these constructors you can avoid the mess by simply bailing out if
31       global destruction is in effect.
