Well, it sounds like WinXP is trying to avoid the nasty consequences of
a dead connection - or it might have something todo with the 'offline
file cache'.  Either way, I think that ignoring the smbecho as
'activity' would probably be a bad idea.

In this case it's a bit of a pity that the cost of processing that echo
is so high, but I can't really see a good way around it.
