The copout would be to use some other database type than skiplist, but you 
may not want to do that, really. I can't offhand think of anything useful 
to suggest that's likely to be effective, but I supose if your mupdate 
connections are cleartext you could tcpdump to capture the traffic too and 
perhaps correlate time, or replay to reproduce. But maybe I can come up 
with a more useful idea.
