The u\bup\bpd\bda\bat\bte\be command can send values to the daemon instead of writing
them to the disk itself. All other commands can send a F\bFL\bLU\bUS\bSH\bH command
When appending a value to a tree node, it is checked whether it's time
to write the values to disk. Values are written to disk if
"now() - First >= timeout", where "timeout" is the timeout specified
