I am against special casing like that: it may give you the false sense of passing the test when it
is actually broken. In other words, having the infrastructure-induced test failure is better than
having the test that allows bugs to creep in. Get more memory on a test machine, and maybe lobby for
jtreg to unhoard some [1].
