No no no, nothing wrong with stackless in the context of Twisted, at 
least as far as this problem is concerned. It's just a fundamental issue 
with context-switching when current, un-stacklessy code isn't expecting 
it. It's not a major issue, like it is with regular pre-emptive 
threading, but it can still be a concern in cases like I pointed out.

Of course, there have been some Stackless bugs that were "exercised" by 
Twisted code, but I think all of the ones I've found and reported have 
been fixed so far. Thanks, Christian.
