I like to know the pros and cons of possible solutions.

Threads are built-in, simple, portable and are working for you now.

The rest are non-portable add-ons, with huge learning curves, that produce complicated, hard to maintain code.

And they don't have a solution to fundamentally blocking apis like DBI.

Your question might make some sense if you had specific problems with the threaded solution, but it seems you are allowing the validity of your working code to be questioned on the basis of its 'coolness' with a particular group of people, who "don't like threads" but can't explain why. That's not good reasoning.

Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.
"Science is about questioning the status quo. Questioning authority".
In the absence of evidence, opinion is indistinguishable from prejudice.
