* retry various system calls on EINTR * retry the rest after a short read (common if there is more than about 1K of output) * block SIGCHLD like system(3) does (note that this does not and cannot work fully in threaded programs, they will need to be careful with wait functions) PR: 90580 MFC after: 1 month
