It's worth noting that I did a lot of work toward that goal (making the 
BufMgrLock more granular) earlier in 2004, but unfortunately wasn't able 
to get it finished before leaving for the summer. I can't guarantee that 
the approach I took was the right one, but if anyone's interested in 
working on this area then it might save some time to start with previous 
work. I want to take another shot at doing this for 8.1, although I 
don't know right now if I'll be able to.
