Subject: How to ensure that a block runs entirely after other threads? (Thread.exclusive does not "work")

Hi, I expected that in the following example code, thread t1 would not
work until the Thread.exclusive blocks ends, but I am wrong:

--------------------------------------
t1 = Thread.new { loop do printf "." ; sleep 0.1 end }

Thread.exclusive do
  puts "entering Thread.exclusive..."
  sleep 2
  puts "exiting Thread.exclusive"
end

t1.join
--------------------------------------


But thread t1 runs every 0.1 seconds so I've don't properly understood
the doc about Thread.exclusive. So, is there any easy way for telling
Ruby "run this block entirely without passing the GVL to other thread
in the middle of the block"?

Thanks a lot.
