I'm only saying that mixing threads and forks is, at best going to be messy and extremely difficult to debug; at worst will never work.

I cannot suggest a better solution to your problem without a clear description of the problem.

So far, I do not understand what you are trying to achieve by using Thread::Conveyor? The example code you have offered is nothing more than the code from the Synopsis of that module with a couple of constants changed to big numbers.

Personally I am not sure what problem Thread::Conveyor is designed to solve. As such I have never found a use the module. I'd also be wary of using it as (as far as I'm aware) it's author is no longer developing it.

I am slowly building a library of good uses for threads, and as such I am always willing to try and come up with working solutions to problems using them. In order to do this, it requires a description of the underlying problem devoid of pre-conceptions of the best way to solve it.

In this case, you appear to wanting to run the compression of several log files in parellel. My problem is, I do not see how Thread::Conveyor helps in solving this? I'm also not sure that there will be much in the way of performance advantage in running this type of process in parallel unless you have multiple cpus, but until I try it, I may be completely wrong on that.

Summary: Re-state the question without the preconseptions of how to solve it and I will willing take a crack at it:
