With splash?

With the same splashoutput device? Of course You can't do that: You need a
different splashOut for every thread at least because of the state. And I
forgot one other point: if You use little cms the poppler isn't thread safe, it
will crashes in that area. One of the points I want to solve somewhere in
futur.
