Rails - Mar 2007 - Funky deadlocking of activerecord thread by Test::Unit ...

Hey Guys,

The following works fine.  TaskInterrupt is a ActiveRecord subclass.

require File.dirname(__FILE__) + ''/../test_helper''

  def test_1
  aproc = lambda{ TaskInterrupt.new.pause(''blue'') }
    threads = Thread.new(aproc) { |r| aproc.call }
    threads.join
    puts "join done"
  end

test_1


However the following yields deadlock errors shown at the end of this
posting.  As you can see the only difference between these two is that
the latter uses the Test::Unit Framework.  Anyone have ideas how I can
workaround / trace this issue?

require File.dirname(__FILE__) + ''/../test_helper''

class TestBlue < Test::Unit::TestCase
  def test_1
  aproc = lambda{ TaskInterrupt.new.pause(''blue'') }
    threads = Thread.new(aproc) { |r| aproc.call }
    threads.join
    puts "join done"
  end
end
