Goodie. That makes things easier for me - there's never going to be any 
issue of whether I need to even _think_ about merging the piece of crap.

In other words - if people want anything like that merged, you had better 
work on cleaning up the locking. Because I absolutely WILL NOT apply any 
of the f*ckign broken locking patches that I've seen, when I've personally 
told people how to fix the thing.

In other words, it's all _your_ problem.
