michael@0 9 <!-- This file tests the saving and loading of memory reports to/from file in
michael@0 10 about:memory in the presence of child processes. It is also notable
michael@0 11 for being an about:memory test that uses the real reporters, rather
michael@0 12 than fake deterministic ones, and so tends to show up problems in the
michael@0 13 real reporters (like bogus negative values). -->
