Quoth "Delaney, Timothy" <tdelaney at avaya.com>:
| ObRant: What the hell is the difference between an "implementation defined"
| feature, and an "undefined" feature? In both cases, a particular
| implementation is free to do whatever it wants. The only possible difference
| I can think of is that "implementation defined" implies that the
| implementation should at least try to do something useful ... and actually
| document what it does.

I think that in the former case, a particular implementation is only 
free to do what it wants the first time.  The second time, it should
do what it did the first time.
