Hm, I think it's fine as it is. Running it in othervm will make sure the test runs in its own vm (see http://openjdk.java.net/jtreg/command-help.html). So within the VM process there should not be any interference by other workload. And we check open files before testing and afterwards, and allow for some margin.

The test has been running in our test setup for several days now, so I think it should be ok. And if worst comes to worse, and we see test noise, we might change the test to manual later on.
