queue_index keeps track of which messages have been published but not written to disk
There are 2 ways queue_index writes something to disk:
- the journal is synced, and
- the journal is flushed (i.e. scattered across many files and those
files closed).
Since queue_index is the same process as variable_queue, we just keep
a list of guids that have been published and we just call an on_sync
handler whenever these are written to disk.
