This is basically the opposite of the slowdown timer. Instead
of trying to keep the PIT ticks in sync with bochs time, we
keep them in sync with REAL time. This is bad because it creates
unreproducible fails, but it's good if you want to run bochs at
maximum speed on your machine. However, bochs will take all of
the available resources from the machine also.
DO NOT use this with the slowdown timer. Results would be
unpredictable.
Fixed a "feature" in pc_system.cc with setting timers to small values
that can cause bochs to hang.
Significantly improved the performance of the new PIT.
It's probably ready to become the default now.
Added a preliminary implementation of the slowdown timer
that Bryce and I had talked about.
Also added a hack to keep the OpenBSD timer problem from filling the log.
The new PIT seems to work, but until some
enhancements are made to the way the timers
and devices.cc work, it'll be slower than
the old one.
