I think this one deserves an explanation as well.
(I know the reason because I got caught by it several years ago,
 but I'm sure other Qt users could benefit.)

Better yet, give us a solution. My application requires
a large quantity of code after the fork, and the inability
to use Qt makes it very painful; I known all of those classes
are there, but I can't use them.
