So far I just assumed kernel-space ugdb is the plan. As I wrote before I do
not know gdbserver too much.
If you check gdb/gdbserver/linux-low.c it is just one big ptrace/wait/\/proc
interface. I would guess it could be more simple with the utrace API at hand.
Catching up with systemtap's 200x higher software-watchpoint performance over
current (local) gdb (described in "[debug-list] Utrace Discussion Notes" off
this list) could be easier with in-kernel gdb I thought.
