      Description

        Current vmTestbase/nsk/monitoring/stress/classload tests contains 24 tests, each running exclusively. This drags the tier4 test times up. There seem to be no reason to run these tests exclusively, though: they complete in reasonable time, are lightly-threaded, and consume the usual amount of memory.

        We should consider enabling parallelism for them and get improved test performance. Currently it is blocked by TEST.properties with exclusiveAccess.dirs directives in them.

        Current run on 18-core machine:
        2011.95s user 201.83s system 356% cpu 10:20.19 total

        Fully parallel:
        2274.02s user 128.64s system 2029% cpu 1:58.39 total
