The standard does not require that functions which are implemented using other interfaces which are cancelation points must themselves be cancelation points. I.e., the standard does not require a specific implementation.Linuxthreads overrides waitpid but not __waitpid, so only the public name is a cancellation point. It also overrides system, so that is made a cancellation point separately. But it does not override popen/pclose, so those use __waitpid with no cancellation wrapper inside or out. Is this how it should be?
