Semaphore Techniques

I'm looking to run a process with a limit of 3 instances, but each
execution is over a crontab interval. I've been investigating the
threading module and using daemons to limit active thread objects, but
I'm not very successful at grasping the documentation.

Is it possible to do what I'm trying to do and if so anyone know of a
useful example to get started?
