   OK, I was miles off. But:
   
   ```
             /* Wait for the DHCPD client to respond to the stop request */
   
             sem_wait(&g_dhcpd_daemon.ds_sync);
   ```
   
   There is nowhere that will sem_post if there are no DHCP clients. This needs 
a guard with some suitable dhcpd status value.
   
   Since this does affect me (and my "empty" code which still stupidly has the 
semaphores...doh!) I will take a look on Monday as it should be an easy fix I 
think?
