When emu_start() is first called, the Uxn struct is uninitialised stack data.
This meant the u->ram pointer would be an invalid address so the program would crash
with a segmentation fault when attempting to free it. By setting it to NULL, we avoid this
because calling free() on a NULL pointer is a no-op.
