198f783f8b - my speed boost changes to main.cc and cpu.cc on June 5 were an improvement 
in performance, but I did not check the debugger carefully enough while
  testing them.  Part of the performance gain in main.cc revision 1.33 and
  cpu.cc revision 1.9 was to allow bochs to stay in the cpu loop forever
  in a single processor simulation.  (In a multiprocessor simulation it must
  quit the loop periodically to give the other procs a chance to simulate
  too.  Cooperative multiprocessing?)  In the process, I restored calls
  to BX_TICK in the cpu loop for 1-proc simulation only, and removed them
  from the outer loop.  (See main.cc, since it was done right.)  However
  I never made the equivalent change in the debugger code, so in the
  debugger, there were ticks coming from the cpu loop and then an
  equivalent number of ticks coming from the debugger code just outside
  the cpu loop.  The result was, of course, that simulation time went
  at 2x the correct rate.  This simulation time speedup was made even
  worse because the continue loop in the debugger would increment ticks
  by one quantum (5 at the time) no matter how many instructions had
  actually been executed.  So in trace mode in particular, the way it was
  implemented before today, cpu loop would run only one instruction at
  a time and the simulation time would get incremented 1+5=6 times!  One
  tick from the cpu loop, then 5 erroneous ticks from the continue loop.
  Anyway, much of this nonsense should be fixed now.  For uniprocessor
  simulations, only the cpu loop does ticks (for best performance).  For
  multiprocessor simulations, the cpu loop exits after one quantum and
  the code that calls the cpu loop gets to increment ticks instead.

9a1364b1f9 - apply patches/patch.consistent2b. Description: 
> This patch fixes a number of debugger problems.
>   - with trace-on, simulation time would pass 5x faster than usual, so
>     interrupts and other timed events would happen at different times
>   - with trace-on, breakpoints were ignored
>   - with trace-on, control-C would not stop the processor and return to the
>     debugger.
>
> This patch changes the execution quantum for the debugger to 1, which means
> that cpu_loop is asked to do one instruction at a time.  This may cause
> bochs with the debugger to be slower than before.
>
> I haven't tested without the debugger yet, so I don't know if the timing
> of events matches or not.

742830f1ab - attempt to clean up the behavior when you run bochs from the 
command line or by double clicking.  Running from the command
  line doesn't really work because of a NULL pointer problem in
  gui/carbon.cc.

e25de5fce0 - check for null gCTable, which I am getting every time I run from the 
command line.  This is better than a bus error IMHO.

6d5c174ec0 - move config.h before the extern "C" { } business so that I can use 
BX_WITH_CARBON in there
- don't include Carbon/Carbon.h.  I assume it was in there just for the
  typedef Boolean

a4ca526eee - add preprocessor tricks that undefine the OUT symbol if it's already 
been defined elsewhere.  This had to be done in the old pit as well,
  so it's not a new problem by any means.
