Right. Thats one solution. Maybe it would be helpful to make a list of
recommended toolkits supporting this properly somewhere.

However, it is not the only way to fix the problem. Since LV2 already uses
message based communication between plugin and UI, all the host needs to do is
put each UI into its own process (like Carla does). Then developers can
continue to use Qt or Gtk with dynamic linking for the UI, without the problems
of pulling conflicting UI toolkits into the host process.
