The difference with 'forever' is the invocation of the 'interact'
command, which apparently gives full terminal control to the spawned
process (QEMU). The good thing about that is that it makes it possible
to enter the Fiasco.OC kernel debugger via the 'Esc' key. Interrupting
QEMU should work with 'Ctrl+x a'.
