Ok, I think I understand what's happening. Pre-patch, resolve_hostname was called from afinet_dd_apply_transport(), which gets called after reload. The patch
moved it to afinet_dd_setup_socket() which only gets called if there is no writer set up - but in case of reload, there is.

This made it so that dest_addr never gets initialised after a reload, and stays at 0.0.0.0. The simple fix is to make sure resolve_hostname gets called
sometime during reload too.
