True, but if a plugin in a multi thread system blocks the others can just
carry on and the blocked plugin can be ignored. Not that I think that
is very useful.
If a single threaded plugin blocks you have to poke the master process
which will have to disable the blocked process, I don't think you could do
this without xruns across the board.
