* Added new thread flag THREAD_FLAGS_ALWAYS_RESTART_SYSCALL. If set, it forces syscall restart even when a signal handler without SA_RESTART was invoked. * Fixed sigwait(): If one of requested signals wasn't already pending it would never wake up. Also, the syscall always needs to be restarted, if interrupted by another signal. * Renamed a bunch of the POSIX signal function implementations which did return an error code directly (instead via errno). Added correct POSIX functions where needed. git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@36054 a95241bf-73f2-0310-859d-f6bbb57e9c96
