IRB.startをt1の前に持って行くのはどうでしょうか？

require "irb"
require "benchmark"

def task(name)
  puts "\n#{name}:%s" % Benchmark.measure{
    a = 0
    200000.times{ a += 1 }
  }
end
task("A")

IRB.start
t1 = Thread.start{ task("B") }
puts "EXIT from irb."
t1.join
puts "t1 finished."
# >> 
# >> A:  0.090000   0.000000   0.090000 (  0.092097)
# >> EXIT from irb.
# >> 
# >> B:  0.090000   0.000000   0.090000 (  0.097652)
# >> t1 finished.
