> Looking in test output I see we can sometimes get stuck waiting on
> sequenceid... The parent issues redo of our semantic makes it so we encounter
> failed append more often around damaged WAL.
> This patch makes it so we stamp sequenceid always, even if the append fails.
> This way all sequenceids are accounted for but more important, the latch on
> sequenceid down in WALKey will be cleared.. where before it was not being
> cleared (there is no global list of outstanding WALKeys waiting on
> sequenceids so no way to clean them up... we don't need such a list if we
> ALWAYS stamp the sequenceid).
