The database abstraction layer (everyone should use one) should be extended to log deadlocks and the SQL which created them. Newer versions of InnoDB won't roll back the entire transaction on deadlock. Instead it will only roll back the rows for the statement which failed, which makes dealing with the deadlocks a lot easier.

Having a value like that monitored would have provided valuable info in the very recent past. Have you applied to get this patch applied to mainline tree?
