Well, the real problem comes into play if your "extension.so" above 
pulls in a different version of something already loaded.  ELF is broken 
that way.  Otherwise... I agree, it's messy.

Then there's really no reason to bother, then.

Of course.  I was merely pointing out that relaytool only supports x86, 
and from looking through it, only dlopen(), so using GModule would allow 
it to work on any platform that glib supports, and hence any platform 
Xfce supports.
