| 9 <!-- This file tests the saving and loading of memory reports to/from file in | |
| 10 about:memory in the presence of child processes. It is also notable | |
| 11 for being an about:memory test that uses the real reporters, rather | |
| 12 than fake deterministic ones, and so tends to show up problems in the | |
| 13 real reporters (like bogus negative values). --> | |
