  You are not handling callbacks ! By driving the registration by 
walking the tree directly instead of by registering subdir when 
gamin provides the directory list, all the event reported by gamin
related to directory content when registering a new watch pile up
on your connection ... untill it stuck. It won't be able to send more 
packet to the server because the server is stuck trying to send packets
to your client, which just ignore those continuing to walk and register
monitors.
  Don't do that or switch off directory lists on new monitors.
