Public bug reported:

IP monitor is a method that is going to be executed in a separate 
process, to monitor the IP addresses changes in a namespace.

This method spawns a thread to read from a socket opened by Pyroute2.
The read function is a blocking method that will end only when the 
socket is closed. To avoid thread starvation that can happen using 
greenthreads, IP monitor should use kernel threads. 

This will increase the resources used but will ensure that no message 
is lost when reading the monitor socket.

Reduced the number of IPs generated in "test_add_and_remove_multiple_ips"
to shrink the testing time used.
