Am I dreaming in thinking that I saw a discussion at some time in the past that there is some flaw with using BigDecimals as reliable* optimistic locking attributes? ..... or was that just NSTimestamps and float/double type values? ..... Google is not helping me to find the answer. Anyone recollect the situation with BigDecimal reliability as optimistic locking attributes?

*reliable = works 100% of the time
