Nit: const char* foo -> const char foo[]

[jkarlin, 2015/03/20 13:50:49]

Done.

You can just initialize these in the initializer list, right?

Done.

It'd be nice for this to test that operations just get scheduled if you're
waiting on Init to complete.

[jkarlin, 2015/03/20 13:50:49]

Done.

[davidben, 2015/03/17 18:47:15]

Likewise, having the RunUntilIdles here means you never test what happens if
many Register/Unregister/etc calls happen in parallel. (You could maybe have
some tests that call into the background_sync_manager_ directly and pass in
their own callbacks?) Schedule a bunch, wait for the last one to fire, and
assert that each callback as called as expected.

(It's fine now, but I assume later you'll want these to assert on the properties
of the registration it returns.)

I'd add an EXPECT_FALSE(GetRegistration) to assert that that it did something.
