  "message": "Improve futex_wake behaviour.\n\nThe current code yields and schedules a new thread if any equal or\nhigher-priority thread has become runnable.\n\nThe new code decomposes these cases.  If a new thread is runnable and\nshould run now, the current thread yields.  If a new thread is runnable\nbut is the same priority as the current thread, the scheduler ensures\nthat a timer interrupt is ready but does not yield immediately.\n\nThis improves the test suite performance by around 2% and a\nproducer-consumer microbenchmark by about 35%.\n",
