> drlvm often hangs in shutdown if the test workload is running daemon threads that don't get into safepoints often. This happens because DRLVM often kills daemon these daemon threads while they are holding important locks (see vm_shutdown.cpp, vm waits for daemon threads to shutdown and if they don't shutdown in time, they are killed).  After that we try to detach the main thread, and can't get through about phantom locked locks.
