Subject: exit() does not do dlclose()?

I'm playing with an application that uses dlopen() to load some libraries. I
use the _init function to set the libraries up. I've also set up the _fini
functions to shut things down.

I see, in the man page, that dlclose() will unload the libraries and call
_fini.

My question is whether or not exit() does the same thing? It currently does
not appear to, although that would seem rather odd to me, given the other
types of cleanup it does.

Is this due to the fact that dlopen() bypasses the 'normal' loader, and 
therefore the cleanup routines can not understand how to get rid of them
correctly?
