For the Dreamcast, having two file descriptors on the same file is no
problem.  However, reading from two places at the same time is not
recommended because of the seek times involved with CD drives.  (This
is what makes The Dig and ComI unplayable on the DC; the resources are
managed so badly that they need to be constantly reloaded from CD
causing disruptive load times.)  Of course, I use "at the same time"
in a loose sense here.  The DC port doesn't even have threads.
