I am looking for the same answer you are. I am running the code on Win32 (Perl 5.8.4). This is my code: 
my @threads;
foreach my $suite (@suite) {
    push @threads, Thread->new(\&runThread, $suite);
}
foreach my $t (@threads) {
    push @outputLog, @{$t->join};
}

sub runThread {
   my $self = Thread->self;
   logInfo("Thread #", $self->tid, " (@_) started...");
   my @output = qx{start JVM instance here};
   checkExitValue();
   return \@output;
}

I had no luck prematurely terminating a thread, and if i kill the program, the threads (JVM instances) are still running utilizing my CPU by 100%. In Programming Perl edition 3 in a Thread Model chapter, they say a way to terminate a thread would be by calling a return in a top-level function, but it didnt quite work for me. I am still struggling. Anyone? Thanks.
