We are trying to move towards the server doing less and less checking for things like disk corruption, and letting the client do it instead (since the client has to do it anyway, no point in the server doing it too). Some people have pointed out that they perhaps do not trust casual users doing initial pulls to figure out what has gone wrong when they receive corrupted data, inform the admins of the problem, etc.

Therefore, it would be nice if the client somehow could send the server a message letting them know that corruption had been detected, before the client disconnected. This could then be logged on the server, where the admins could see it.

This is somewhat complicated by the fact that we don't generally have specially separated out "consistency checking code" -- inconsistencies are simply signaled by hitting invariants. One solution would simply arrange that if we hit an invariant while we are talking on the network, we dump a description of the invariant to our peer before dying.
