> Simple class unloading scenario shows that DRLVM leaks memory (and finally crashes).
To reproduce, run StressTest of lazy.test suite and watch that process gradually consumes
more and more memory. If compared to RI, the last keeps memory flat during very long runs.
> Memory leaks roughly in the same rate for any execution mode, compiled or interpreted.
> For convenience, there is standalone launcher org.apache.harmony.vm.test.lazyresolution.StressTest
which can vary stress load, e.g.: 
> working_vm$ cd build\windows_x86_msvc_release\tests\lazy.tests\classes 
> classes$ java -cp .;junit.jar -Dlazy.test.iterations=100 -Dlazy.test.threads=10 org.apache.harmony.vm.test.lazyresolution.StressTest
