I doubt it writes to fd 5 - instead, it will open a few files/sockets/pipes
and writes to them. One of them happens to get the 5 assigned as
filedescriptor. Figure out which one (I guess you used strace to get that
number the firest hand?), and if it's a file, just read the contents of it.
If its anything else, I'm pretty much out of ideas, but maybe others
aren't.
