Ah, sorry I didn't say it clearly. I didn't mean there is no problem to
unload the modules. I meant we could use the
gnome_accessibility_module_shutdown functions to disable accessibility.

As the previous mail I sent, it is possible to enable accessibility
without session restart. For disable, it depends on how we do it. It is
possible to deregister the applications from registryd in
gnome_accessibility_module_shutdown function, but unloaded the modules
will cause applications crash.
