Hullo again :)

I'm unfamiliar with postgres development practices, so this is more a 
request for information than anything else.

It's been about a month since the last activity on bufmgr as documented 
on the hackers list and I was just concerned that this issue had been 
filed as an interesting toy at the time, but now left for the circular 
filing cabinet :)

Tom + Simon were able to see a fairly easy 25% performance boost against 
our dataset and I'd obv. be very keen to see this work make it into 
8.1.4 or 8.2.0 :)

Cheers,
Gavin.
