This was just an awesome writeup, Mike, thanks a million!

I know that this sort of analysis comes up fairly frequently,
when advanced users are trying to analyze their application
behavior, and understanding the effects of things like
isolation level, index usage, etc. are quite tricky.

It would be great to capture this information into our
product docs somehow. I thought about trying to just yank
Mike's message into the wiki, but it doesn't really work so
well as a standalone doc.

Does anybody have any ideas about how we could capture some
of this info about topics like scan locks, key ranges, bulk
index fetches, etc. into our existing lock documentation?
