Dear Monks, In my Perl/Tk code, I have a auto-refresh functionality which calls a function whose job is to update the canvas with the latest network topology. I am using repeat: 
    $autorefresh_id = $root->repeat($rinterval*60000,\&refresh_func);

[download]
$rinterval is the auto-refresh interval (in minutes) set by the user. The question is this: the refresh_func() could take some time to run depending upon the size of the network. If a user sets the refresh interval ($rinterval) to a time less than the time it takes to refresh the display, I assume that it would lead to issues since the same variables will get overwritten if refresh_func runs before the preceding function has returned. What would be the proper mechanism to handle this? Thank you in advance...
