Signals now cause an event, and there's a way to continue until the next signal. I can see this being used for detection of `int3` although I'm not entirely sure as it may prove being too late to stop abortion of process.

Redox OS Microkernel
Debugging the redox kernel
Running qemu with the -s flag will set up qemu to listen on port 1234 for
a gdb client to connect to it. To debug the redox kernel run.
make qemu debug=yes
This will start a VM with and listen on port 1234 for a gdb or lldb client.
gdb
If you are going to use gdb, run the following to load debug symbols and connect to your running kernel.
(gdb) symbol-file build/kernel.sym
(gdb) target remote localhost:1234
lldb
If you are going to use lldb, run the following to start debugging.
(lldb) target create -s build/kernel.sym build/kernel
(lldb) gdb-remote localhost:1234
Debugging
After connecting to your kernel you can set some interesting breakpoints and continue
the process. See your debuggers man page for more information on useful commands to run.
