in reply to Non-blocking IO and threads

This code will hang at count = 10 until something is read from the command prompt. How do I avoid this block?

That isn't what happens running your code on my system. I waited until the count reached 14 the typed 'x' 3 times and ^C once:

c:\test>junk85 test, count:0 test, count:1 test, count:2 test, count:3 test, count:4 test, count:5 test, count:6 test, count:7 test, count:8 test, count:9 test, count:10 test, count:11 @test, count:12 @test, count:13 test, count:14 x->120 @test, count:15 x->120 test, count:16 x->120 @test, count:17 Terminating on signal SIGINT(2)

Hard to advise on how to avoid something that doesn't happen?

    What if I tell you I'm using ActiveState 5.8 on a Windows machine?
      I, too, am seeing a "hang" at "test, count:10" (under Activestate 5.12.4/Windows XP). And I must note that I'm not seeing that "hang" under Ubuntu-"Natty Narwhal".

      I used AS 5.10.1 on Windows above. I just tried it with AS 5.8.9 and it blocks as you describe.

      I do not have an explanation for that, but the work-around is obvious. Upgrade.
