TestNG tests appear to hang with latest lambda

[Ben Evans]

OK, following up to my own mail.

The tests will actually complete if left for long enough, but the
process gets *huge* - at least 2.8G in size, and if other processes
are running, it will take a very long time to complete.

Does anyone have any insight as to why the tests consume so much memory?
