Yes - it's still broken because I still haven't fixed it :-(

Fixing Atropos is still on my todo list.  One of the other developers is 
working on an alternative deadline-based scheduler, which may behave better.

I don't know where the bug is - it appears to be something quite subtle since 
the code *looks* OK to the people who have read through it...  Analysing some 
trace buffer output might help us figure out what it's actually doing and 
why.

I'd still like to look at this myself but you're welcome to take a shot at 
debugging it if you're feeling enthusiastic!

Cheers,
Mark
