Traceback (most recent call last):
  File "/usr/bin/tuna", line 710, in <module>
    main()
  File "/usr/bin/tuna", line 592, in main
    spread = spread)
  File "/usr/lib/python2.7/site-packages/tuna/tuna.py", line 275, in move_threads_to_cpu
    print >> stderr, "thread %(pid)d cannot be moved as requested" %{'pid':pid}
NameError: global name 'stderr' is not defined


Version-Release number of selected component (if applicable):

tuna-0.13-6.el7.noarch


How reproducible:

Always
