8 // This object may be accessed from many different threads. It will be accessed | |
9 // most often from the syncer thread. However, when update application is in | |
10 // progress it may also be accessed from the worker threads. This is safe | |
11 // because only one of them will run at a time, and the syncer thread will be | |
12 // blocked until update application completes. | |
13 // | |
14 // This object contains only global state. None of its members are per model | |
