the previous post asked for working examples... it's difficult to cut out brief parts

Though it may be difficult, it's a good training exercise for you in learning Perl. The act of creating a small cut-down program should help you focus on and better understand the problem; you may even find you're able to identify the problem and fix it yourself.

BTW, instead of your global NS file handle and the:

select (NS);
$|= 1;
select (NS);

claptrap, you should use a lexical file handle ($ns say) and then simply:

use IO::Handle;
# ...
$ns->autoflush();

With recent Perls (5.8+), there's no need anymore to confusingly change the (global) default destination for print statements via the old evil one-argument form of select -- for more details, see Perl Best Practices, chapter 10 and Perl tip: Buffering and IO::Handle (for Perl 5.14+ you don't need use IO::Handle).

Suggest you further read Suffering from Buffering.

Thank you for the feedback and document references!
I'm going to continue to read the Lincoln Stein Book, will check out the Best Practices book as well.
I have read the Suffering from Buffering! A good read, indeed :).
