Right, ok, you're actually one of the special cases where the framework
overhead actually does matter then. Sorry, 99% of the people benching
hello world aren't so I tend to assume :)

There are two things you can do then - (1) throw Devel::NYTProf at your
app and see if there's a specific bit of Catalyst that needs optimising,
which we'd be happy to help with, (2) take HTTP::Engine and Path::Dispatcher
and roll your own, treating Catalyst as your fast prototyping tool.

Well, if Catalyst wasn't threadsafe we'd hear screaming from the people
on win32, so in the absence of screaming I'm happy to assume it is :)
