+ * In POSIX a signal is sent either to a specific thread (Linux task)
+ * or to the process as a whole (Linux thread group).  How the signal
+ * is sent determines whether it's to one thread or the whole group,
+ * which determines which signal mask(s) are involved in blocking it
+ * from being delivered until later.  When the signal is delivered,
+ * either it's caught or ignored by a user handler or it has a default
+ * effect that applies to the whole thread group (POSIX process).
+ *
+ * The possible effects an unblocked signal set to SIG_DFL can have are:
+ *   ignore     - Nothing Happens
+ *   terminate  - kill the process, i.e. all threads in the group,
+ *                similar to exit_group.  The group leader (only) reports
+ *                WIFSIGNALED status to its parent.
+ *   coredump   - write a core dump file describing all threads using
+ *                the same mm and then kill all those threads
+ *   stop       - stop all the threads in the group, i.e. TASK_STOPPED state
+ *
+ * SIGKILL and SIGSTOP cannot be caught, blocked, or ignored.
+ * Other signals when not blocked and set to SIG_DFL behaves as follows.
+ * The job control signals also have other special effects.
