yeah, it's been on my todo list for some time... decided that it stayed
rotting for too long. We also did a little test program to exercise wich
is how I discovered the subtle difference between BookE and server.

Any comment about my approach of making BookE "look like" server by
sticking a single step in there ? IE. Is the semantic of stopping on the
-target- of the branch what userspace expects ?

Cheers,
Ben.
