While this works for you, it's a bad practice. Why? Because other people using
your code may not have these modules loaded from startup.pl.

perldoc -f require
It gets loaded only once. Why should be any difference with threadpool.
Application-wise it's all transparent.

Won't loading them for every handler put an instance of it in
memory over and over again though? Or will Perl realize that
its already loaded and not load it again? How would this behave
in MPM threadpool?
