It makes the code so much simpler. And quite probably faster as there's less malloc/free churn. A lot of problems break down to: * we need this effectively forever (i.e. until config reload) * we need this very briefly when processing a task or request Sometimes you need a cache that has intermediate lifetimes, but that is a much smaller problem to deal with, and you can often cope with manual memory management for that Hook any file handles and other resource cleanup functions into the same pools and you have a pretty easy life.
