- * (Getting the lock is not really necessary, since we expect that this is

- * only used during single-process XLOG replay, but some subroutines such

- * as MarkBufferDirty will complain if we don't. And hopefully we'll get

- * hot standby support in the future, where there will be backends running

- * read-only queries during XLOG replay.)

+ * (Getting the buffer lock is not really necessary during single-process

+ * crash recovery, but some subroutines such as MarkBufferDirty will complain

+ * if we don't have the lock. In hot standby mode it's definitely necessary.)

* The returned buffer is exclusively-locked.
