Sorry about the vague title and the short code example, but I'm not sure what's going on here and this seems to be the crux of the matter. I have the following chunk of code. 

print " -- executing: $component_name  " . ($force_flag ? "(forced)" :
+ "") . " ($component) \n";

my $thr = threads->create( sub {
        my $passed_component = shift;
        print "STARTED: $component_name  ($passed_component)\n";
        $passed_component->execute($current_time);
        print "FINISHED: $component_name (at $current_time)\n";
    }, $component
);

When run it produces the following output... 

 -- executing: MYCOMPONENT  (Scheduler::Component=HASH(0x1dd4244))
STARTED: MYCOMPONENT  (Scheduler::Component=HASH(0x21bca9c))

For the life of me, I can't figure out why the two object refs are different.

It's causing a problem because the Scheduler Component object set it's last run time at the end of the execute function, but I can't see that value as I seem to be looking at the wrong object! What I'm finding even harder to understand is that I've only created one Scheduler::Component object, so have no idea where this other reference has come from.

I did put a print of $self in the new() call for Scheduler::Component, which runs before the lines shown above, and shows the value for the component outside the thread. 

CREATED NEW COMPONENT (Scheduler::Component=HASH(0x1dd4244))

Any help much appreciated.
