Bug #10009

Updated by normalperson (Eric Wong) over 5 years ago

I created this issue #9832 but not have io operation. 
 In the script attached I simulate IO operation in multi-thread environment. 
 For ruby 1.9.2 apply `taskset -c -p 2 #{Process.pid}` for regulates threads behavior. 
 The second Thread is a io operation
