Whether to write/send access_log records ASAP or accumulate them and
	then write/send them in larger chunks. Buffering may improve
	performance because it decreases the number of I/Os. However,
	buffering increases the delay before log records become available to
	the final recipient (e.g., a disk file or logging daemon) and,
	hence, increases the risk of log records loss.

	Note that even when buffered_logs are off, Squid may have to buffer
	records if it cannot write/send them immediately due to pending I/Os
	(e.g., the I/O writing the previous log record) or connectivity loss.

	Currently honored by 'daemon' access_log module only.
