Zoran> Hi Uwe !

Dear Zoran,

many thanks for your contribution!

Zoran> Basically, the global_objects array is now member of the runtime
Zoran> state so as the errorCount (the only one local static!!).

I see the point for errorCount, but global_objects is only 
initalized once and never written. Therefore, it should be safe
to keep it global. Do i miss something?

Zoran> Did test on Solaris 2.5.1 with Purify 4.2 and it seems to work

Thanks for the Purify test, this is good news (we have no Purify).

Zoran> Hey, I like the idea of putting the runtime state in
Zoran> global NS clientData. This IS a good trick !

we did not have much other options.

Zoran> PLS, check wether this is ok for you. You might include it
Zoran> in the standard distro if you like (I'll appreciate it, so
Zoran> I don't have to patch it for any new version.:)

we are in the process of rolling out 0.83, your
patches should be included in this verison.

Zoran> BTW, new versions...
Zoran> o. do you plan to modularize the xotcl.c? It's grown big!

we have done some first steps, but it will take some more time.

Zoran> o. the 1.0 version: if? when? what functionality planned?

the forthcoming version comes with "inst mixins" which are
similar to per-object mixins, but on the class level. instmixins 
make it easy to intercept e.g. the predefined methods of Object.
