| * A LocalStorage-based mutex. Guarantees¹ that only one browser window will be | |
| * able to execute the code inside the callback at a time. | |
| * | |
| * Based on the Alur and Taubenfeld fast lock | |
| * (http://www.cs.rochester.edu/research/synchronization/pseudocode/fastlock.html) | |
| * with an added timeout to ensure there will be eventual progress in the event | |
| * that a window is closed in the middle of the callback. | |
| * | |
| * 1. The guarantee assumes that the algorithm is correctly implemented. |
