Note that this has probably been happening for a very long time. The test system just doesn't detect the problem (see #2113).

I'm not 100% sure what this test is supposed to do. It has Carpet::enable_no_storage = yes, so it shouldn't be trying to allocate memory. The test machine has 4 GB of RAM. This could be increased, but we probably don't want to have a test in the ET that requires so much memory.
