I had a different goal of marking them weak. But looking at the specs about the cancellation point functions I can read the following: "Cancellation points shall occur when a thread is executing the following functions:" fcntl, close, related to wait6 (wait, waitpid, waitid), write, writev From the another commit about asctime: "A cancellation point may also occur when a thread is executing the following functions:" asctime() http://pubs.opengroup.org/onlinepubs/009695399/functions/xsh_chap02_09.html
