Considering that this is a big and somewhat invasive patch series, I'm all for 
being conservative on it. I.e. please take your time on reviewing it. I'm 
pretty sure there are some things that need to be improved on, e.g. my usage 
of the rbtree code. I'm a C++ dev, this C-style copy'n'paste programming for 
containers is foreign to me.

Cheers
