The behaviour you're seeing sounds odd (which is hopefully encouraging :-),
but it's not clear from the description whether its a bug

Yes, this works really well in python and it's lots of fun. We've found so

If the poshmodule had a bit of TLC, it would be extremely useful for this,
since it does (surprisingly) still work with python 2.5, but does need a

We build applications in Kamaelia and then discover afterwards that they're
