With the previous patch, the CSN generator was not updated. The server with the greater timestamp could issue update operations that the consumer could not "overrule".

With the new patch, the csn generator on the consumer is immediately updated.

Note that with this patch, if there is some sort of ntp or vm problem that causes a large system time difference, the large time skews will be immediately propagated everywhere.

We need to figure out some way to safely "repair" or "reset" the CSN time generator, or, figure out some way to avoid large time skews altogether.
