Is there any actual user-visible feature that depends on this, or is 
this solely for debugging and development purposes?

It would of course be *nice* to have it in stable trees (particularly so 
we pick it up in distros) but I'm not convinced that enabling HW 
breakpoints on a platform where it has *never* worked qualifies as an 
"actual bug".

(BTW many thanks for fixing this - I had a shot at it late last year but 
never quite got there!)
