SVN rev 200721 on 2009-12-19 11:13:59Z by kib
MFC r198506:
In kern_sigsuspend(), manipulate thread signal mask using
kern_sigprocmask(). Also, do cursig/postsig loop immediately after
waiting for signal, repeating the wait if wakeup was spurious due to
race with other thread fetching signal from the process queue before us.
MFC r199136:
Use cpu_set_syscall_retval(9) to set syscall result, and return
EJUSTRETURN from kern_sigsuspend() to prevent syscall return code from
modifying wrong frame.
Take care of possibility that pending SIGCONT might be cancelled by
SIGSTOP, causing postsig() not to deliver any catched signal.
