There's no need to test this more than once. Add a NOHANG flag which can be used to specify that a subtest can not be run when hanging. If it's set on either the subtest or the mode, the -hang test for this combination will not be generated.
Changes since v1: - Merge the patch that renamed HANG to NOHANG. - Rebase after 'reorganize subtests by type'. - Allow subtests to specify NOHANG too. Changes since v2: - Mark accuracy test with NOHANG, gpu reset disables interrupts, causing the test to fail.
