I suppose this should be reported but .... under load slurpd has in the
past lost updates for me. This has always happened when there are > ~10
slaves and higher than average update rate say >1 change a second.
Anyone else seen this ? Its very hard to replicate as its random and as
such I haven't ever found any hard proof as to why it happened. The most
important symptom was that the change never even got attempted according
to the logs on the affected slaves.
