It's been awhile since I played concurrently with descriptors and
streams, but I thought I recalled that the only real issue was that they
were using the same descriptor, so operations on one affected the other,
as opposed to a dup() of a file descriptor, which keeps track of two
sets of data about the file, two modes, two pointers, etc.
