 Let's do persistent 24 bit session ids (4 chars, ~16M  possible). This is instead of
 jumping through all the hoops of constantly changing them. Only upon the first
 usage of the database in a client instance (local database initialization) do
 we need to secure a unique id. We just need to keep a little bit of local
 state, such as an object in e.g. APPDATA_PATH/netfs/sid.
 
-Now we can do these 2 operations in a row, wrapped in a Promise:
-1) get_next_id
-2) increment_next_id
-
-We know that if another session id is set between these 2 steps, then
-increment_next_id won't work, and we won't have any gaps in the ids.
