It may be possible that the socket is not the one that belongs to the 
dispatcher. For example if you run the dispatcher with --no-fork, so it 
won't create a pid file, then while it is running you start another one 
which will refuse to start because the control port is already in use, it 
will still delete the old socket (connected to the 1st dispatcher) and 
create a new one. While it may look like it is there, it's not the socket 
from the 1st dispatcher, so it's not the socket you can use to talk to 
it. It's just a dangling socket that is not connected to anything.

If you run the dispatcher as a daemon and it creates a pid file, then the 
2nd instance will detect that and won't even attempt to start, so it 
won't delete the 1st instance socket.
