It's more heavyweight than just setting the registers, but it's quite
easy to add specific unwinders for syscalls, exceptions, interrupts...
And this works very nicely (well, the real difficulty is to have GDB
load the debug information for the appropriate userspace task, but
that's maybe not an issue in your case).
