Thanks very much!

I've decided to go straight to 8.1 though.  There are just too many  
performance improvements at this point that I might regret not having  
and I don't want to do a dump reload again.  I am about to compile it  
now.  If it isn't a panic grade failure in the latest 8.1 code then  
I'd just assume take the stock release source code.  I don't care at  
all if this kills one connection at the ultra-low frequency with  
which it occurs but what I can't have is the whole server rebooting  
itself in the middle of processing hundreds of transactions.  Once  
that happens all of the web clients hang onto their bad connections  
and then eventually die.  Considering that I'm moving to 8.1 and am  
not too familiar with applying patches am I crazy for just going with  
the stock 8.1 code?
