9d03795a15 Wire up the netlink socket to the epoll handler. Still need to actually 
react to events in the processing function.
Pass the client_state structure to the netlink code explicitly rather than
making it a global variable.

a53a82bbc5 After fork(), a signalfd-created file descriptor still returns signal info 
for the parent.  Close and recreate a new signalfd after forking into the
