Subject: [BUG?] SystemExit & abort_on_exception in latest "ruby_1_8"

Hi!

I have noticed a change in the effect of Thread.abort_on_exception in 
the latest "ruby_1_8" version in CVS, compared to 1.8.2. The following 
script works differently:

---------------------------------------
   Thread.abort_on_exception = true

   begin
       Thread.new do
           raise "boom"
       end
   rescue SystemExit
       puts "SystemExit caught ....."
   end

   Thread.pass
   sleep 10
   puts "AT THE END ..."
---------------------------------------

The output in the two versions are:

   $ latest-1.8/bin/ruby  jh-thread.rb
   jh-thread.rb:5: boom (RuntimeError)
           from jh-thread.rb:4
   $
   $ 1.8.2/bin/ruby  jh-thread.rb
   jh-thread.rb:5: boom (RuntimeError)
           from jh-thread.rb:4:in `initialize'
           from jh-thread.rb:4:in `new'
           from jh-thread.rb:4
   SystemExit caught .....
   AT THE END ...
   $

Is this change intentional, or a bug?
