daemon: start working on events. notes:

Browse Source 
Probably need to make the locking mechanism more granular. Only lock the
database during db writes, see if we can do multiple readers and a
single writer. Otherwise, the daemon will not be able to service
requests while an event is being handled, which is not good.
