My impression of Tom's suggestion was that it would also be a maximum
amount of delay which would be allowed before killing off queries- not
that it would be able to wait indefinitely until no one is blocking.
Based on that, I don't know that there's really much user-seen behaviour
between the two, except in 'oddball' situations, where there's a time
skew between the servers, or a large lag, etc, in which case I think
Tom's proposal would be more likely what's 'expected', whereas what you
would get with the existing implementation (zero time delay, or far too
much) would be a 'gotcha'..
Thanks,
Stephen
