Description

Perl 5.15 adds a new phase during global destruction which invokes
DESTROY on unreferenced SVs. This is causing a tripwire exception
when VTable's DESTROY method gets called (VTable_Destroy() should
never be called). However, the fix is more involved than simply
disabling the tripwire.
