~"open(2)...shall return...the lowest non-negative available file descriptor

variable errno shall be set to indicate the reason for failure."~
Considering that it's been thus since (time_t *) &UNIX[VERSION_6]; I
really don't expect it to change any time soon. EVERYbody's programs
depend rather heavily on these semantics, whether they realise it or not.
Aside: It took me a moment to figure out why this happened:
$ exec >&- 2>&-
echo foo | tee bar
exec >&0 2>&0
$ cat bar
...until I remembered the semantics of open().
NetBSD. Not Guano.
