Reviewed by Chris Dumez.

Generally speaking, an auxiliary process wakes up because a new activity was added to its activity
set. Instead of just logging that we are resuming the process, we should also log the activity
name. This helps us debug whether or not the process wakeup is reasonable or spurious.
