Just revisited this, and it looks like this problem has been fixed in 2.7.1. In particular, with the test case provided, we now get the desired output:

<unittest.suite.TestSuite tests=[<unittest.suite.TestSuite tests=[<module.sometest.SomeTest testMethod=testOne>, <module.sometest.SomeTest testMethod=testTwo>]>]>
<unittest.suite.TestSuite tests=[<unittest.suite.TestSuite tests=[<module.sometest.SomeTest testMethod=testOne>, <module.sometest.SomeTest testMethod=testTwo>]>]>

I believe this problem was fixed with https://hg.python.org/jython/rev/dcff83c1c4ac, which directly addresses overly eager collection of PySystemState, because of the use of weakrefs.
