It looks like we're limited to a single thread for the GUI, at least
under Windows:

  http://developer.gnome.org/doc/API/2.0/gdk/gdk-Threads.html
  http://bugzilla.gnome.org/show_bug.cgi?id=60620

I think multithreaded dissection and supporting multiple capture files
in the same Wireshark instance are both important, but that the need for
multithreaded dissection will become more acute as time goes on.  If
Intel's plans come to fruition, we could be looking at dissecting on a
single core while 79 others sit idle.
