- Introduce __assert_disable global - Improve strsignal() thread safety - Make system call tracing thread safe - Fix SO_RCVTIMEO / SO_SNDTIMEO on Windows - Refactor DescribeFoo() functions into one place - Fix fork() on Windows when TLS and MAP_STACK exist - Round upwards in setsockopt(SO_RCVTIMEO) on Windows - Disable futexes on OpenBSD which seem extremely broken - Implement a better kludge for monotonic time on Windows
