PROBLEM:	(TKTR70408, QAR 47306)	(Patch ID: OSF415-400092)
********
This problem affects only Digital UNIX systems using C-list-type tty's.
If a user attempts to log into such a system remotely, using either telnet
or rlogin, and kills the remote-access application (telnet or rlogin) during
the login procedure (at the "Password:" prompt) then the rlogind or telnetd
process will be left in a sleep state indefinitely.  This condition can be
recognized by the presense of rlogind or telnetd processes in the process
table with no associated remote user.

PROBLEM:        (HPAQ95241, QAR 50022)  (Patch ID: OSF415-405042)
********
This patch fixes a problem that causes the system to "assert_wait" panic and
the stack contains streams modules.

A representative stack trace is:

panic(s = "assert_wait")
assert_wait_mesg                sched_prim.c
pts_close                       pty.c
close_wrapper                   str_subr.c
csq_protect                     str_synch.c
osr_pop_subr                    str_osr.c
osr_close_subr                  str_scalls.c
pse_close                       str_scalls.c
speclose                        spec_vnops.c
clearalias                      spec_vnops.c
exit                            kern_exit.c
psig                            kern_sig.c
trap                            trap.c

********
The system can panic with "kernel memory fault."  This is a timing-related
panic.  The following is a typical panic trace:

>  0 boot() 
   1 panic(... = "kernel memory fault") 
   2 trap() 
   3 _XentMM()
   4 simple_lock_B() 
   5 pgrp_ref() 
   6 exit()
   7 rexit() 
   8 syscall()
 9 _Xsyscall()
