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