Comment (by Phyx-):

 There's nothing contradictory about what's on the website. It takes 3
 flags to make it threaded. Also as the replies said, you can make it the
 default for your exe so you don't have to specify it when running the
 application.

 Surely calling `Control.Concurrent.setNumCapabilities` on startup or using
 `-with-rtsopts` isn't that prohibitive..
