PROBLEM:  (TKTRB0985)    (Patch ID: OSF440-037)
********
This patch fixes a kernel problem, where proper locking/reference
count management was not being performed. This could result in a
panic with the stack trace:

        5 panic(s = 0xfffffc0000777888 = "lock_terminate: lock held")
        6 lock_terminate
        7 pgdelete
        8 pgrp_unref
        9 pgrm
        10 proc_teardown
        11 waitf
        12 wait4
        13 syscall
        14 _Xsyscall
