Ruby 1.8 threads are not proper threads and will never work. If we want to 
integrate Ruby 1.9 threads then it should be possible, and some patches were 
posted on this list a month or two ago. QtRuby badly needs a bit of 
restructing, and doing Ruby 1.9 threads properly would be an important part of 
that. I started working on a restructure a month or two ago. If I check it 
into the kdebindings trunk it won't compile and people will complain. Don't 
know what to do about that until we switch to git. I think we should be 
posting threading patches on reviewboard so they don't get lost too.
