It's a _damn_ good point, but I see we went ahead and merged sys_epoll_pwait without it anyway -- despite the fact that it's include/linux/eventpoll.h which contains the example of why we should think first :) I think I even threw together an untested implementation of compat_sys_epoll_pwait() at one point to assist with that task, but it didn't seem to help much. -- dwmw2
