Hello,

Over the past few days I've seen on and off failures on RubyInstaller CI related to (({test_autoclose_true_closed_by_finalizer})):

http://ci.rubyinstaller.org/job/ruby-trunk-x86-test-all/265/console

 1) Error:
 test_autoclose_true_closed_by_finalizer(TestIO):
 NoMethodError: undefined method `close' for 2012-11-07 04:43:41 -0300:WeakRef
 C:/Users/Worker/Jenkins/workspace/ruby-trunk-x86-build/test/ruby/test_io.rb:1611:in `test_autoclose_true_closed_by_finalizer'

This seems to happen when the system is under heavy load (because is running other jobs in parallel).

This might be a hint of something not working properly under heavy load, perhaps the GC in effect.

I was unable to produce the same failure on x64-mingw32, and haven't tried yet OSX or Linux.

Any ideas?
