Hi Sawada-san,

Thanks! Rebased and attached. The only changes are: the LWLock
tranche is now shown as "serializable_xact" instead of "sxact" (hmm,
LWLock tranches have lower_case_names_with_underscores, but individual
LWLocks have CamelCaseName...), and ShareSerializableXact() no longer
does Assert(!IsParallelWorker()). These changes are based on the last
feedback from Robert.
