Mario,
This is done when iterating over all of the fd’s of a
process to attempt to determine which fd’s are real
file descriptors and then to get the pathname information
(if possible) on the file descriptors by using iofdinfo().
I think that we could probably get away with not doing
the dup(), but I’d have to ask the developer what the
rational was for that in the first place. I suspect that
it is just another sanity check.
