Bug #6664: Object finalizer do not run until program exit
https://bugs.ruby-lang.org/issues/6664

Author: funny_falcon (Yura Sokolov)
Status: Open
Priority: Urgent
Assignee: 
Category: core
Target version: 2.0.0
ruby -v: ruby 2.0.0dev (2012-06-28 trunk 36243) [x86_64-linux]


Test script: https://gist.github.com/3009867

Conclusions:
- Ruby 1.8.7 (REE) is able to run finalizer on GC when its proc is created outside of scope and so that does not handle object in its binding.
- even Ruby 1.8.7 not able to run finalizer until program exit when finalizer's proc is created in scope where #define_finalizer is called
- neither Ruby 1.9.2, nor Ruby 1.9.3, nor Ruby-trunk is able to run finalizer until program exit.
