First, you should have a look at the first reply on your node. I think there's some valuable information in there.

Second, I'm glad you at least put <CODE> tags around your code but a little more layout won't hurt. For example: just use white lines to separate the parts of code (variable initialisation and different parts of the real code) :) This is not meant to assault you in any way, it's just offered as an advice.

Thirth thing, think about what you're actually trying to achieve. For example:
my $old_fh=select(STDOUT); $| = 1; select($old_fh);
default, STDOUT is selected. So, $old_fh refers to STDOUT now. Then you select STDOUT and make it to flush automatically. Then, you select $old_fh which refers to STDOUT. I really had a hard time while trying to understand what you was actually trying to do here.
Again, not trying to assault you, but what you're doing here is just: $| = 1 in three lines, where the other two lines only are like "Hey MUBA, what is your nick name?".
