Crash during WAL recovery?

This snippet in xlog.c makes we wonder...

	else if (ControlFile->state == DB_IN_RECOVERY)
	{
		elog(LOG, "Data Base System was interrupted being in recovery at %s\n"
			 "\tThis propably means that some data blocks are corrupted\n"
			 "\tAnd you will have to use last backup for recovery",
			 str_time(ControlFile->time));
	}

I thought this was going to be crash safe.
