Its not that simple.. "pkg load <package>" doesn't reload a package (ie 
install on the path) if it is already installed. However, what it does 
do is recursive check all of the dependencies of <package> to see if 
they are loaded, and is very careful of the order in which packages are 
placed on the path to handle the case that two packages install a 
function with the same name or that the newly loaded package uses the 
dependent package in its PKG_ADD file..

I'd be happy to see "pkg" sped up, but am unsure of the best way to go 
about this..
