Hello All,

Within a Perl Tk script I am executing a number of after commands that may execute at the same time.

$me->get_top_frame()->after(3000,sub {$me->monitor_jobs()});

I need to restore some environment during each 'monitor_job' execution, so I need the other after cmds to wait till the current one is complete (there may be multiple monitor_jobs executing at the same time).

I was thinking that the 'after' command was executing separate threads so I was planning to use 'Thread::Semaphore' module however that seems to block.

Is Perl a thread language and if not, what is the Thread::Semaphore module for?

Does anyone have a suggestion on how to control the execution of the after commands so they do not over lap. I would really rather not have to have one scheduler controller for them. It was really nice being able to execute the after cmds independently.

Thanks in advance
