Would you have any document about MDB, or project-site url? I think it is hard for anyone to understand what you like to do only from these big patchset.

Would you have talked with kdb/kgdb people? Since linux kernel already have kgdb, I think you might better talk about merging your functionality (and stability) to kgdb, or at least talk about what part both debugger can share.

Out of curiously, is there anyone except for you using MDB?
