I am not sure if I understand your question, but sheep_get_fd() will NOT
call connect_to() for free cached FDs. Only if all the cached FDs of one
node are all used by other threads, it temporarily create a new
connection that will be closed by subsequent sheep_put_fd(). This design
prevent FD from being concurrent accessed by more than one threads at a
time.

Thanks,
