Autotimers and Description Uniqueness

[birdman]

The code is clearly not supposed to do this, there is a test for it, but it's screwed up. Maybe the code I posted before and then lost confidence in is the fix:

It's a fix for something - although the actual fix should be more like:

 retValue = extdesc1 == extdesc2 

with relevant handling of any Null values.
However, that something is only a small subset of cases - it's not going to have any effect on most of the cases in this thread.
