ltdl resident modules are unloaded by lt_dlexit()

[Bob Friesenhahn]

I have a module which uses a library which sometimes registers an 
atexit() handler to clean itself up.  If lt_dlexit() is invoked, then 
any modules loaded by libltdl are then unloaded.  Unfortunately, when 
the module is unloaded, the library it referenced crashes due to the 
atexit().  I tried using both lt_dladvise_resident() and 
lt_dlmakeresident() to mark the module as resident so that it can not 
be unloaded, but the program still crashes at exit.  It is not clear 
to me if the module was still unloaded, or if the problem is that the 
library it depends on was still unloaded.

Thoughts?
