I sure don't like the idea of a successful load of "osex" NOT populating 
some table with a well known set of functions. If sleep() is part of 
osex, then it should be there if the load is successful.

I am liking the idea of 'require "osex"' populating the real 'os' table, 
if it exists. If not, osex should load the equivalant of the functions 
from 'os' and then add its own and return that table. That way 'osex' is 
always a superset of 'os' and all the functions are in one place. In 
fact, I have never seen any implementations where 'os' is supplied as a 
loadable module, so why not just name this extension 'os' and always 
have it include the proposed functions as well as those in the existing 
'os' package?
