It's matt's new storage thingy ready for you to use yet?

[Matt Perry, 2012/06/15 18:59:34]

It's ready in asynchronous form. Do we want to move events+filters to the
storage too? That means we'll have to block startup on loading the event
registrations out of the database.

I think leaving this stuff in Preferences is kinda just as bad at this point.

I lean toward putting all our new state in level DB and blocking things that
need to be blocked when necessary.

Ok, I'll work on making that change in this patch then.

[Matt Perry, 2012/06/18 23:35:46]

It's more work than you might think. I would hold off for a future patch.

I'm not entirely convinced moving to level DB is a good idea. If something needs
to be read while blocking startup, it doesn't buy us anything to move it out of
Preferences (which blocks startup). That just adds 1 more file that blocks
startup.
