| At the moment Olsrd has no support for multithreading. Instead of locking the

| add_olsr_socket() function with an additional parameter called "realtime":
| 
| void add_olsr_socket(int fd, olsr_bool realtime, void(*pf)(int fd));
| 
| This way a plugin can decide if it needs to be contacted directly when a 
| package arrives or if it can wait for the next polling cycle.
| 
| In the olsr_scheduler_sleep() function we can use a select() statement to wait 
| for packages from all realtime sockets while using the timeout parameter to 
| wait for the next polling cycle.
| 
| I think this sollution will be as flexible as a locking mechanism without 
| needing support for multithreading at all.

looks good to me - no objection. - /hannes
