$thr->suspend();
$thr->yield();
Given that it is proceed by: $thr->join(); which means that the thread no longer exists by the time the above two lines are executed. In addition, the ->yield() method of the threads module isn't exported by default, and you do not import it.
Your code is exactly equivalent to: #!/usr/bin/perl
use strict;
use warnings;
$|=1;
my $TERM = 0;
$SIG{'INT'} = $SIG{'TERM'} = sub { $TERM = 1; };
print "To terminate program, hit ctrl-^C\n";
print( join(' ', ()) );
sleep (1) until ($TERM);
In other words it does exactly nothing useful and is in no way an answer to the OPs question.
Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.
"Science is about questioning the status quo. Questioning authority".
In the absence of evidence, opinion is indistinguishable from prejudice.
