On my system, the device and inode number are the same in the initial
state - I assume because both stderr and stdout are being sent to the
same tty, but I assume they have different file table entries in the
kernel because stderr can be set to nonblock without doing the same to
stdout. I need to know when the two file descriptors point to the same
file table entry (i.e. $ cvs <whatever> 2>&1).
The flags available via fcntl() appear to be identical in both cases as
well.
