Well, I should have written not _yet_ for 11.00 and maybe 10.20. I 
am/was not able to test on these systems since I don't have them.
Sorry for not being more clear here.

Great!

Then we should consider these getting into svn too, right?

From our discussions I meant to have learned that 11.11 is the only 
system which works reliably. Maybe 11.00 too, but I think there we need 
some more investigations in the 100 failures.

But from the effort point of view I guess 10.20 support is a bit high.
Sure, if somebody wants this we can try to make it work. But I guess the 
threads are a big hurdle?

Thanks for the clarification.
