Synopsis: System locks after pty pair "broke"

State-Changed-Why: 
Fixed in revision 1.31 of kern/vfs_subr.c.  vclean() needs
to do a nonblocking close to avoid the hang, and the
nonblocking flag that it used (IO_NDELAY) had become
inconsistent with the nonblocking flag that ttylclose() 
accepts (FNONBLOCK).
