Summary of Changes

Hello @chandra-siri, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request focuses on enhancing the robustness of system tests by addressing potential resource leaks. It introduces mechanisms for explicit garbage collection and object deletion at the conclusion of tests involving AsyncMultiRangeDownloader and AsyncAppendableObjectWriter instances. Furthermore, a new diagnostic tool has been integrated to monitor system resource usage, specifically open TCP connections, providing better visibility into test-related resource management.

Highlights

• Explicit Resource Cleanup: Explicit calls to del for writer and mrd objects, followed by gc.collect(), have been added at the end of several system tests to ensure prompt garbage collection and resource release.
• Resource Monitoring Utility: A new helper function, log_num_of_open_fd, has been introduced to monitor and log the number of open TCP connections, aiding in the diagnosis of potential resource leaks during test execution.
• Test Refactoring: The write_one_appendable_object helper and appendable_object fixture have been commented out, and the object creation logic for test_mrd_open_with_read_handle has been moved directly into the test for more explicit control over object lifecycles.
