Thanks for your consideration. This is caused by the timer thread. It's not easy to remove the timer thread completely, however in ruby-core:32686 [1] I submitted a patch to only use the timer thread when it is required to schedule Ruby threads. With that patch, the timer thread is not used in single-threaded applications. Feedback on my approach to this problem would be greatly appreciated, since this is an important issue for me. The code seems sound, but perhaps there are some intricacies I've missed. Any thoughts? 1. http://blade.nagaokaut.ac.jp/cgi-bin/scat.rb/ruby/ruby-core/32686
