Thanks,
What happens if
use vars qw(%list ....)

%list being a hash of sockets like
%list{listName}->socketObject;

Then I use the sockets in subroutines like
sub sendToList {
send stuff to all $list{listName}->socketObjects;
...
}

Would that be okay with no memory leaks, or would it hold on to the socketObjects even after delete $list{listName} ?
Would it be the same for
http_request (
...
,sub {
send stuff to all $list{listName}->socketObjects;
});

Closure stuff seems difficult for me to grasp :(
Again thanks for your reply.
