       Perl's global destruction is a little tricky to deal with WRT finalizers because it's not ordered and
       objects can sometimes disappear.

       Writing defensive destructors is hard and annoying, and usually if global destruction is happening you
       only need the destructors that free up non process local resources to actually execute.

       For these constructors you can avoid the mess by simply bailing out if global destruction is in effect.

       This module uses Sub::Exporter::Progressive so the exports may be renamed, aliased, etc. if Sub::Exporter
       is present.

       in_global_destruction
           Returns   true   if   the  interpreter  is  in  global  destruction.  In  perl  5.14+,  this  returns
           "${^GLOBAL_PHASE} eq 'DESTRUCT'", and on earlier perls, detects it using the value of "PL_main_cv" or
           "PL_dirty".

       Devel::GlobalDestruction - Provides function returning the equivalent of "${^GLOBAL_PHASE} eq 'DESTRUCT'"
       for older perls.

           sub DESTROY {
               return if in_global_destruction;
