- A set of improvements to various futex self tests
- Conversion to the selftest harness
- Provide and use thread creation and synchronization helpers to reduce
the dependency on delays, which tend to fail on loaded test systems
- New tests for validating owner exit scenarios for robust and PI futexes
- Runtime detect supported features and skip the tests if the kernel
has no support
- A few minor fixes

reduce the dependency on delays, which tend to fail on loaded test
systems
- New tests for validating owner exit scenarios for robust and PI
futexes
- Runtime detect supported features and skip the tests if the kernel
