I think it would be good to implement a feature that shows how this
approach is an improvement over the current state of gdb+ptrace or
gdb+gdbserver.
Exactly what feature this should be... I don't know :-)
I would imagine something performance-related.
There was previously some discussion about some watchpoint-related
thing, I forget the details of that.
I don't think thread-specific breakpoints are exposed outside of gdb
yet. If that is true, then implementing that would mean adding remote
protocol features and also other stuff inside gdb. So, I would suggest
not tackling this yet.
