2123 INFO TEST-UNEXPECTED-FAIL | chrome://mochitests/content/chrome/toolkit/devtools/server/tests/mochitest/test_memory_gc_01.html | undefined assertion name - expected PASS
The failing test is <http://mxr.mozilla.org/mozilla-central/source/toolkit/devtools/server/tests/mochitest/test_memory_gc_01.html?force=1#35>.

It seems like this test is testing for something that is impossible to assert.  There are a ton of reasons why we may be allocating memory in a way that the total measurement after a GC is more than before.  And also we cannot guarantee that a GC doesn't occur before the test initiates one.

I think the test needs to be rewritten to assert that this eventually happens, not that it happens every time.
