8 noexcept-specifier from std::condition_variable::wait and gave the new
10 std::condition_variable::wait(unique_lock<mutex>&)@GLIBCXX_3.4.11 as an
11 alias for a new symbol, __gnu_cxx::__nothrow_wait_cv::wait, which still
12 has the incorrect noexcept guarantee. That __nothrow_wait_cv::wait is
13 just a wrapper around the real condition_variable::wait which adds
17 __nothrow_wait_cv::wait calls the condition_variable::wait function it

14 a handful of situations where the driver needs to wait for buffers to

41 and dies. Hence Wait-Die.
42 There is also another algorithm called Wound-Wait:
46 transaction. Hence Wound-Wait.
48 However, the Wound-Wait algorithm is typically stated to generate fewer backoffs
49 compared to Wait-Die, but is, on the other hand, associated with more work than
50 Wait-Die when recovering from a backoff. Wound-Wait is also a preemptive
