Debugging user-space in system emulation
========================================
While it is technically possible to debug a user-space program running
inside a system image, it does present challenges. Kernel preemption
and execution mode changes between kernel and user mode can make it
hard to follow what's going on. Unless you are specifically trying to
debug some interaction between kernel and user-space you are better
off running your guest program with gdb either in the guest or using
a gdbserver exposed via a port to the outside world.
