You mix things a bit.

My approach allows to either using netlink or kernel hotplug method, 
sharing the code and invoking only one instance of the parser / handler 
even on hotplug event bursts. The third method is the initial device 
file system population

Splitting this into different processes is the Unix way of multi 
threading, using fifo (= named pipe) for inter process communication.
