- NOTE_TRACK has never triggered a NOTE_TRACK event from the parent pid.
If NOTE_FORK is set, the listener will get a NOTE_FORK event from
the parent pid, but not a separate NOTE_TRACK event.
- Explicitly note that the event added to monitor the child process
preserves the fflags from the original event.
- Move the description of NOTE_TRACKERR under NOTE_TRACK as it is not a
bit for the user to set (which is what this list pupports to be).
Also, explicitly note that if an error occurs, the NOTE_CHILD event
will not be generated.

EV_RECEIPT is useful to disambiguating error conditions when multiple
events structures are passed to kevent(2). The error code is returned
in the data field and EV_ERROR is set.

When the EV_DISPATCH flag is used the event source will be disabled
immediately after the delivery of an event. This is similar to the
EV_ONESHOT flag but it doesn't delete the event.

Add user events support to kernel events which are not associated with any
kernel mechanism but are triggered by user level code. This is useful for
adding user level events to an event handler that may also be monitoring
kernel events.

the data value returned by kevent()'s EVFILT_READ filter on non-TCP
sockets accurately reflects the amount of data that can be read from the
sockets by applications.
