socket could be acquired, ie. when its reference count is 0, it cannot be acquired anymore. This requires the protocol to do proper locking, though. * The TCP EndpointManager now checks the return value of acquire_socket(), and only returns the endpoint if that succeeded. * This fixes bug #2197. * Minor cleanup. git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@30363 a95241bf-73f2-0310-859d-f6bbb57e9c96
