Along these lines, would it be faster to use LWP::Parallel, even though it is a bit heavier and slower, to fetch requests in parallel, or to use something like HTTP::MHTTP and fork() or Thread, and grab the requests from @urls one-at-a-time?

My concern here is that I'll have an array and some hashes that have urls that are seen, unseen, down, bad, and so on.. and I need to make sure that the process putting urls into the hashes and arrays (as links are yanked from the pages in %seen) can be fetched by processes already in fork() or registered in parallel. Would this require some sort of shared memory to get working properly? Can a forked process read and write to an array or hash created by the parent of the fork?

I've got a lot of this code "functioning", but now is the time to refactor and get the performance up to speed (pun intended) for a production distribution of the tool.
