The test used a real-time sleep to move the queued permit into the preemptive-abort window. If the reactor did not get CPU for long enough, admission could run only after the permit's timeout had expired, making the expected abort path flaky. The test also exhausted memory together with count resources, so the queued permit could wait for memory. Preemptive abort is intentionally not applied to permits waiting for memory, so keep enough memory available and assert that the permit is queued only on count. Use an immediate preemptive-abort threshold and a long finite timeout to exercise admission-time abort without relying on scheduler timing. Fixes: SCYLLADB-1796 Closes scylladb/scylladb#29736

If you can use an existing folder, consider adding your test to it. New folders should be used for new large categories/subsystems, or when the test environment is significantly different from some existing suite, e.g. you plan to start scylladb with different configuration, and you intend to add many tests and would like them to reuse an existing Scylla cluster (clusters can be reused for tests within the same folder).
To add a new folder, create a new directory, and then
copy & edit its suite.ini.
