Sharing the same listening socket can be a serious bootleneck for most UNIX
systems. To my mind, it is recommended to have a process listening to
requests and who is the unique owner of the listening socket. This process
will dispatch the work to a set of other processes which will send the
requested objects.
We must not also use heavily IPC mechanisms as they can lower performance
even in SMP computers (some implementations of IPC need to halt all the
processors while accessing to a semaphore for example).
