Re: unloading/reloading an asdf system

Hi Craig,

ASDF keeps track of the load time and compile time of the files in a  
system, not the consequences of actually loading those files (which  
would be very hard, IMHO). As far as ASDF knows, you loaded the files  
already and so it doesn't need to load them again even after you  
delete the package.

FWIW, I _don't_ see the same behavior as you do. Here is part of  
session in MCL with moptilities:

I wasn't able to try this with parenscript because HTMLGEN 404'd  
while I was trying to install. However, parenscript's ASDF system  
definition doesn't appear to have anything the least bit odd in it so  
I don't see why that would be the difference. Do you see this  
behavior with other systens?
