Tom Lane 0a51e7073c Don't take ProcArrayLock while exiting a transaction that has no XID; there is 
no need for serialization against snapshot-taking because the xact doesn't
affect anyone else's snapshot anyway.  Per discussion.  Also, move various
info about the interlocking of transactions and snapshots out of code comments
and into a hopefully-more-cohesive discussion in access/transam/README.

Also, remove a couple of now-obsolete comments about having to force some WAL
to be written to persuade RecordTransactionCommit to do its thing.
