>Description:

kgdb behaves much the same as gdb from a user I/O perspective.  However,
I've run into a number of nits, including:

- When multi-page output occurs, such as "info threads" on a kernel core,
  you somtimes cannot use 'q' to quit from the list, despite the --more--
  prompt text indicating that you can.  On the other hand, sometimes it
  does work...?

- Ctrl-Z appears not to suspend the kgdb session, but does for gdb.

- When an xterm is resized, kgdb doesn't notice, so the pager will stop
  long or short of the current window size.

>How-To-Repeat:

kgdb kernel.debug /var/crash/vmcore.8
(etc)
