but shared texts (which weve enjoed since very early BSD releases) does
the same thing! the real selling point of shared libs is to save disk,
to be able to update your programs wihtout recompiling them by updating 
a library instead. with shared text only one copy of the text is resident
anyways! 
ok ok ok ill grant ya that  there is the one copy of a lib function at a time
in memory, but that payoff isnt that big.. its in disk where it saves a lot of
space... 
ymmv

happy hacking
