Thanks for the pointers. This seems to work. I did notice that an error was raised when I tried to kill a detached thread, but joining after a kill seems to work. I still need to watch the memory cleanup, but I'm relieved that the basics are working.

Works on linux. Notice the 'exit' => 'threads_only'; 

#!/usr/bin/perl
use warnings;
use strict;
use threads 'exit' => 'threads_only';

print "I'm the parent pid-> $$\n";
my $thr = threads->new(\&sub1);
#my $thr1 = threads->new(\&sub2)->detach; # issues a warning on kill
my $thr1 = threads->new(\&sub2);


for(1..15){
   
   print "$_\n";
   
   if( $_ == 5 ){ $thr->kill('KILL')->join } 
   if( $_ == 10 ){ $thr1->kill('KILL')->join }
   
   sleep 1;
 }

exit;

sub sub1{

my $myobject = threads->self;
my $mytid= $myobject->tid;

$SIG{'KILL'} = sub{ print "tid $mytid exiting\n"; threads->exit() };

print "In the thread $myobject tid->$mytid \n";
my $count = 0;
while(1){ 
   $count++;
   print "\t\t\t$mytid -> $count\n"; 
   sleep 1;
  }
}

sub sub2{

my $myobject = threads->self;
my $mytid= $myobject->tid;

$SIG{'KILL'} = sub{ print "tid $mytid exiting\n"; threads->exit() };

print "In the thread $myobject tid->$mytid \n";
my $count = 0;
while(1){ 
   $count++;
   print "\t\t\t\t\t$mytid -> $count\n"; 
   sleep 1;
  }
}
