Master client freeze when another client try to connect with wrong connect-id
Steps:
- launch a server
./pvserver --multi-clients
- launch a client ("client1")
./paraview
- connect client to server.
- launch another client ("client2"), with a wrong connect-id
./paraview --connect-id=42
Server and client2 print error message due to wrong connect id. But client1 does not respond anymore.
Note that connecting another client correctly will unlock client1.
