I am not entirely sure what you are proposing, but the point you will
need to bear in mind is that because libsigc++ does not do its own
locking/synchronisation, with Glib::Dispatcher the same thread has to
connect, disconnect and execute the slot.  Any other thread can emit of
course (which is the point of the having a Glib::Dispatcher class) -
Glib::Dispatcher::emit() does not invoke any libsigc++ functions.
