[9fans] XaoS - first threaded version

[Jan Hubicka hubicka@horac.ta.jcu.cz]

Hi
Last weekend I god threaded version of plan9 port working (using spinlocks
and rendenzvous) Please if you have SMP box, try it and let me know
how it works/performance tests. It is available at 
http://www.ta.jcu.cz/pub/linux/hubicka/experimental/xaos30zf.tgz
XaoS with threads can be started xaos -threads <n>
Performance should be mesasuer using key 'L' - it prints number of frames
per second. So you should do tests as follow:
Start XaoS and press 'L' it will display framerate of calcualting first image
(usually low)
start zooming - numbers will fly around. Let me know number approx half of
second after start.
Let me know speed in -threads 1 and -threads <higher number :)>

Also XaoS still don't have image saving code. I think wrbitmapfile don't
fit my needs, since it don't have any way to specify colormap.
I don't save resulting image (since it should be dithered etc) but image
in my internal structures instead. So please if possible, let me know
code to save 8bpp/32bpp(troecolor) image with palette.

Last question is where to install XaoS? /386/bin/xaos and /sys/lib/XaoS
for shared data?
