Yes I measured this in the past. I'll repeat this experiment tonight with 1.6.1 so I have numbers to 
compare with numbers I sent in reply to John.

I think it's faster because without tests library.zip is about 3-4MB less in size. So it's not 
because something imported, but because of side effect of loading this fat big library.zip every time.
