The primary reason is because of the desire to have the REPL: if GUI is on 
another thread, then REPL is "alive" whlie the GUI is running, you can 
manipulate objects, redefine functions, etc. and have the GUI respond to 
changes (not to all kinds of changes, of course, but e.g. you can redefine the 
function that is called by GUI without having to close windows and restart 
application).

This is somewhat explained in recently updated version of tutorial at 
http://common-lisp.net/project/cl-gtk2/tutorial.html (in the "Main loop" 
section).

As far as I know, the only problem this creates is the requirement that the 
lisp must be multi-threaded. As for SBCL and Clozure CL on Linux, CCL on Mac, 
Allegro it should work fine (don't know about clisp)

I guess that on OS X it should work. I am not so sure about Windows, however; 
it will require some work.
