From looking at the IIS.net forums, people wanted a solution where
they could use MS new FastCGI DLL in much the same way PHP is. Yes the
scripts code is compiled each time, but Perl is already loaded and the
process re-used. It's not intended to give you all of FastCGI's
benefits, just some of them, it's supposed to be a drop in replacement
for their CGI.
Thanks for pointing out the clean execution environment, this will
cause a problem for global variables in the script... I'd appreciate it
if someone would point out the fastest way of giving each call a clean
environment, so that globals from scripts called in this manor are not
left behind...

My bad, but with such as small script, what would you test for?

I'll be giving the IIS people a guide for proper FastCGI's with Perl,
but that isn't the intention of this module.
