No you're not:

>>> IF ! STRNCMP (filename, "/proc/self/fd/", 14)  THEN
>>>           fopen(filename, "r")
>>> ELSE
>>>          fdopen(atoi(filename+14), "r")
>>> FI

If the filename starts with /proc/self/fd/, qemu will
not try to open that file but parse the rest of the
string as a filedescriptor number.
