- mc146818's rtcintr() no longer has a monopoly on statclock().
- In profiling mode, the statclock() will drift very slightly

found in pfsync_insert_state(). It is caused by two packets which happen
to belong to the same session. Think of UDP stream or two TCP SYN packets
transmitted almost simultaneously. The first such packet wins a state lock
and inserts state to table. The second packet waits for state lock
as a reader. As soon as the first packet is done with state creation
it drops the lock and is going to sent S_INS message to its peer via
pfsync. The second update meanwhile obtains the state lock as a reader.
It finds a state created by the first packet. Later the second packet
also finds out the state needs to be updated, because sync_state
is still set to PFSYNC_S_NONE. The second packet puts state to snapshot
list marking it as S_UPD. All this happens before the first packet has
a chance to make a progress. Think of the first packet loses cpu after
dropping a write lock. Once the first packet gets running again it
trips KASSERT() because sync_state is set to S_UPD.
