Justine Tunney	022536cab6	Make futexes cancellable by pthreads	2022-11-04 18:36:34 -07:00
Justine Tunney	2278327eba	Implement support for POSIX thread cancellations ... This change makes some miracle modifications to the System Five system call support, which lets us have safe, correct, and atomic handling of thread cancellations. It all turned out to be cheaper than anticipated because it wasn't necessary to modify the system call veneers. We were able to encode the cancellability of each system call into the magnums found in libc/sysv/syscalls.sh. Since cancellations are so waq, we are also supporting a lovely Musl Libc mask feature for raising ECANCELED.	2022-11-04 01:04:43 -07:00
