Title: RETAINING TASK EXIT STATUS
Description: When a task exists, its exit status should be retained in
so data structure until it is reaped (via waitpid(), or
similar interface) or until the parent thread exists.
You would think that this should be a clone of the existing
pthread join logic. Howver there is no need for zombies
in NuttX so no need to keep the status if the parent has
already exit'ed. Other simplifications:
1. Keep the array/list of return status in the parent
tasks TCB.
2. Use a fixed size array of return status (perhaps the
the enire array is allocated so that that is con
penalty for tasks that have no childre.
At present, exit status is not retained. If waitpid()
is called after the child task has exit'ed it simpley
returns with the ECHLD error. That is not too bad, but
does not tell you what the exit status was.
A work-around is to:
1) Call sched_lock() to disable pre-emption.
2) Start the task (it cannot run because pre-emption is
disbled.
3) Call waitpid();
4) Call sched_unlock() to re-enable pre-emption.

important interfaces. For the average user, these
functions are just fine the way they are.
Title: execv() AND vfork()
Description: There is a problem when vfork() calls execv() (or execl()) to
start a new appliction: When the parent thread calls vfork()
it receives and gets the pid of the vforked task, and *not*
the pid of the desired execv'ed application.
The same tasking arrangement is used by the standard function
posix_spawn(). However, posix_spawn uses the non-standard, internal
NuttX interface task_reparent() to replace the childs parent task
with the caller of posix_spawn(). That cannot be done with vfork()
because we don't know what vfor() is going to do.
Any solution to this is either very difficult or impossible with
an MMU.

Title: net_poll() DOES NOT HANDLE LOSS-OF-CONNECTION CORRECTLY
Description: When a loss of connection is detected by any logic waiting on the
networking events, the function net_lostconnection() must be called.
That function just sets some bits in the socket structure so that
it remembers that the connection is lost.
That is currently done in recvfrom(), send(), and net_monitor.c. But
it is not done in the net_poll() logic; that logic correctly sets
the POLLHUP status, but it does not call net_lostconnection(). As a
result, if recv() is called after the poll() or select(), the system
will hang because the recv() does not know that the connection has
been lost.

Title: RE-DIRECTION OF BUILTIN APPLICATONS
Description: There is a problem with the re-direction of output form built-in
applications in NSH. When output is re-directed, exec_builtin()
spawns a tiny trampoline task that re-directs the output as
requested, starts the built-in task and then exit.
The problem is that when exec_builtin() starts the trampoline task,
it receives and returns the pid of the trampoline task, and *not*
the pid of the desired builtin application. This bad pid is returned
to NSH and when NSH tries to use that pid in the waitpid() call, it
fails because the trampoline task no longer exists.
The same tasking arrangement is used by the standard function
posix_spawn(). However, posix_spawn uses the non-standard, internal
NuttX interface task_reparent() to replace the childs parent task
with the caller of posix_spawn().
exec_builtin() should not use this internal interface, however,
since it resides in the application space. The suggested solution
is (1) move the exec_builtin() logic into nuttx/sched, (2) make it
a semi-standard interface renamed to task_spawn() and prototyped
in nuttx/include/sched.h, and then (2) use task_reparent to solve
the parental problem in the same way that posix_spawn does.
