I expect no CPU intensive algorithms, so a single thread and a single
process look like the best approach. If such an algorithm would be
needed I'd probably use a few worker threads to execute them, but I'd
not use one thread per connection/request.

But is DBD suitable for talking to an app server?
It could be if it's generalised to RPC.

But that's not usable due to the requirement of independence from Apache.
