Additionally after this failure lots of other tests are experiencing:
execvp: Too many open files

The above report is for 2.6.21-1.3228.fc7 x86 SMP

On 2.6.20-1.2962.fc6 x86_64 SMP the failure mode is different:

1) testASMSingleStep(frysk.rt.TestStepping)junit.framework.AssertionFailedError:
event loop run explictly stopped (Attempting to add attachedObserver)

   at frysk.junit.Runner.runCases(TestRunner)
   at frysk.junit.Runner.runArchCases(TestRunner)
   at frysk.junit.Runner.runTestCases(TestRunner)
   at TestRunner.main(TestRunner)

And no execvp errors afterwards.

I've broken this bug into separate and more specific problems.
