>Description:
Any X based Tk/Tcl program will cause the keyboard to freeze 
under X Windows when the Tk/Tcl program exits.  I have tracked the
problem to a change made to /usr/src/sys/kern/tty.c on Nov 22 by bde
where he made the following change:

o Handle c_ispeed = 0 to c_ispeed = c_ospeed conversion here instead
of in drivers and fix drivers that write to tp->t_termios.

The system does NOT freeze, a Ctrl-Backspace will exit X and the system 
now responds as normal.  Duplicated under X 3.3.2 and 3.3.3.
>How-To-Repeat:
Run any Tk/TCL based program (either the 4.x or 8.x versions).  Exit the
program and the keyboard will lock under X.  May be hardware dependent.
I have duplicated on two different systems:  Pentium 233 w/64meg RAM, 
IDE HD, SVGA X Driver.  Pentium II 300 w/128meg RAM, IDE HD, SCSI HD,
SVGA X Driver.  Both systems have Matrox display adapters.
>Fix:
Backed out the change to tty.c and everything works fine.  Could be that
updates to drivers (which ones?) may be required before tty.c change 
can become effective?
