>Description:
	pppctl aborts with

	Fatal error '_waitq_remove: Not in queue' at line 317 in file /usr/src/lib/libc_r/uthread/uthread_priority_queue.c (errno = 35)

>How-To-Repeat:
	Start up two windows.

	Window 1:
		# ppp
		Working in interactive mode
		Using interface: tun0
		# ppp ON machine> set server /tmp/s ""

	Window 2:
		# pppctl /tmp/s
		# ppp ON machine> set log local command

	Window 1:
		# ppp ON machine> show who
		.......

	You may need to do the ``show who'' more than once - on one occasion
	here I needed to do it twice.

	Window 2 eventually shows:
		ppp ON machine> Command: /dev/tty: show who
		Fatal error '_waitq_remove: Not in queue' at line 317 in file /usr/src/lib/libc_r/uthread/uthread_priority_queue.c (errno = 35)
		Abort trap (core dumped)
		# 

>Fix:

	No idea, I know little about the pthreads implementation.  It's
	always possible to use telnet instead of pppctl though, so this
	problem can't really be described as critical...
