What are the alternatives to Perl interpreter threads?

Question

perldoc threads says:

The use of interpreter-based threads in perl is officially discouraged.

Are there any other Perl based threads

Answer 1

That warning is poppycock. It should be removed. The developers of Perl explained that it means "The use of interpreter-based threads in perl is officially discouraged if you want a lightweight system for multitasking".

Since creating new threads can be expensive, just use a model that involves reusable worker threads.
