Seeing significant perf degradations running the Java PVR tests now, presumably due to unrelated changes that have gone in since I opened this PR.
I can't get through a run of all the tests without a hang; [in some (all?) cases it seems that Docker is running out of space in its virtual filesystem](https://gist.github.com/ryan-williams/45f3b8e4f67aca28acbc2f1ee733fd47#file-gistfile1-txt-L17). Previously all 200+ cases ran in a bit over an hour, but now it grinds to a halt about 50 cases in (always on a different test case, n=3) in about an hour.
