A long time ago, in a galaxy far far away, ‘threads’ were a programming novelty rarely used and seldom trusted. Using a connection pool in each module is hardly efficient: Even with a relatively small number of modules, and a small pool size in each, you end up with a lot of server processes. Context-switching between them is costly.
