@shipilev I have experimented with adding a periodic GC (every 5 seconds) in a new thread, and it did not affect the run time of the test. It still timed out at `CONF=linux-x86_64-server-fastdebug make test 1371.53s user 14.98s system 112% cpu 20:31.41 total` with the removal of the `-XX:-VerifyDependencies` flag.

I will submit an amended commit with this test removed from the ProblemList.txt.
