you're right, there's no difference. for typical usage this is not a big deal, 
since you usually don't reload different versions of a package all the time. 
only if your writing/debugging a package it's a real nuisance to restart the 
whole application over and over again, for each and every smallest change you 
made and want to check the outcome.

simply unloading and reloading a package doesn't work (therefore i wonder what 
the package removal feature in R could be used for at all?), as well as is 
saving and restoring the workspace with RKWard. 

when i understood that you put the instance of R into a seperate process, i 
was wondering if it would be possible to use that to elegantly solve the above 
issue. i'm thinking of being able to restart the R engine alone, without the 
need to quit RKWard. it would be really great for package development, if you 
just had to press a button or call some rkward.R.restart() function to cleanly 
"reload" the whole recent workspace in a new instance of R. the just added 
functions to save/open your session might be of use here as well, as somehow 
RKWard would need to preserve your working enviroment (opened script files 
could remain as they are, but things like help pages and editor windows would 
have to be refreshed at least).

can you follow me?
