I have to agree with you that it all works pretty well, that is why I like using threads. I did some more realistic testing and found that the threads were collecting garbage alot better than I thought they would. In this more realistic script, the memory holds steady. I don't know why my previous experience with threads showed otherwise..... maybe it was because I was using guis, (non-thread-safe Tk) or older Perl versions? Possibly I was leaving non-detached threads in an unjoined condition, OR had threads which were hanging somewhere in their code? 
#!/usr/bin/perl
use warnings;
use strict;
use threads;
use threads::shared;

my $count = 0;

while (1) {
        $count++;
        print "thread $count started\n";         
        my $t = threads->new(\&do_my_thing, $count)->detach;
        sleep 5;
    }


sub do_my_thing {
    
    use LWP::Simple;
    use Data::Dumper;
    use HTML::TokeParser::Simple;
   
   my $get = 'http://google.com';
   my $page=get( $get );

   my $p = HTML::TokeParser::Simple->new( \$page );
    while ( my $token = $p->get_token ) {
       # This prints all text in an HTML doc (strips HTML)
           next unless $token->is_text;
       print $token->as_is;
      }

    my $val = shift;
    select(undef,undef,undef,.1);
    print "thread $val ended\n";         
}
