Ok, but I'm wondering if there is something else I should be doing to 
execute the actual preload. It seems that all I do here is give Embperl 
an array, but when I enable the preload, it just goes through everything 
suspiciously quickly. I don't think it's actually executing anything at 
preload time, though I could be wrong. I'm thinking there's something 
else I need to do to tell Embperl "ok, now actually load all those files"...
