What do you think is the point of this code?:

$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.

In the absence of evidence, opinion is indistinguishable from prejudice.
