I think you're confusing two notions here. What you're talking about
sounds more like dynamic loading, not dynamic linking. And with dynamic
loading the control is *explicitly* at client's possession. You're
supposed to know what to dlopen, what to look for inside, etc. Such
a controlled environment lets you be much more precise and avoid
many of the shortcomings of the true "dynamic linking".
Now, it would be interesting to know what others think about the need
for dynamic loading in Plan9.
Personally, my dream has always been to make all of the applications
which rely heavily on console input-output to be dynamically loaded
on top of each other, so that when I do something like:
$ bash
<long session with bash, with lots of useful stuff in history and such>
$ gdb
I don't leave shell (and lose all of the context) but I rather have
my shell augmented with gdb commands. Sort of like Tcl works with
external modules.
Have anybody thought about anything likes this ?
Thanks,
Roman.
