        I intend to review this patch, if nobody else gets to it.
        
I considered it a new optimization, hence didn't submit it for 4.0
review.  I've thought about it a couple of times since then, but never
got around to sending you a note :-) 

It ought to be pretty safe if you want to add it to 4.0, it improves a
number of things, not just perl.   Probably should have been done a long
time ago, I just never thought of this solution before for some reason.
:-)

I'll do a mainline version of it today, although I doubt its any
different than the tcb version.  I'm not aware of any out-of-ssa
variations between tcb and mainline.
